As a little bit of background. I want to fill a column with jsonb values using values from other columns. Initially, I used this query:
UPDATE myTable
SET column_name =
row_to_json(rowset)
FROM (SELECT column1, column2 FROM myTable)rowset
However, this query seems to run for way too long (a few hours before I stopped it) on a dataset with 9 million records. So I looking for a solution with the second FROM clause and found the jsonb_insert function. To test the query I first ran this sample query:
SELECT jsonb_insert('{}','{column1}','500000')
Which gives {'column1':500000} as output. Perfect, so I tried to fill the value using the actual column:
SELECT jsonb_insert('{}':,'{column1}',column1) FROM myTable WHERE id = <test_id>
This gives a syntax error and a suggestion to add argument types, which leads me to the following:
SELECT jsonb_insert('{}':,'{column1}','column1')
FROM myTable WHERE id = <test_id>
SELECT jsonb_insert('{}'::jsonb,'{column1}'::jsonb,column1::numeric(8,0))
FROM myTable WHERE id = <test_id>
Both these queries give invalid input type syntax error, with Token 'column1' is invalid.
I really can not seem to find the correct syntax for these queries using documentation. Does anyone know what the correct syntax would be?
Because jsonb_insert function might need to use jsonb type for the new_value parameter
jsonb_insert(target jsonb, path text[], new_value jsonb [, insert_after boolean])
if we want to get number type of JSON, we can try to cast the column as string type before cast jsonb
if we want to get a string type of JSON, we can try to use concat function with double-quotes sign.
CREATE TABLE myTable (column1 varchar(50),column2 int);
INSERT INTO myTable VALUES('column1',50000);
SELECT jsonb_insert('{}','{column1}',concat('"',column1,'"')::jsonb) as JsonStringType,
jsonb_insert('{}','{column2}',coalesce(column2::TEXT,'null')::jsonb) as JsonNumberType
FROM myTable

Note
if our column value might be null we can try to put 'null' for coalesce function as coalesce(column2::TEXT,'null').
I want to execute MERGE query in BigQuery tables which contain numeric column.When I used below query to execute I am getting error as Query error: Value of type FLOAT64 cannot be assigned to Numeric, which has type NUMERIC.
In my case, Its not possible to recognize datatype of number fields otherwise I can cast as per datatype of column.
Query =
MERGE Target T USING
(SELECT * FROM (SELECT 874 as ID,1012.0 as numericVal) S ON T.numericVal= S .numericVal WHEN MATCHED THEN UPDATE SET ID= S .ID,numericVal = S .numericVal
WHEN NOT MATCHED THEN INSERT ROW;
If you are not able to change the source, try casting as numeric and it'll be rounded accordingly
SELECT 874 as ID, CAST(1012.0 as NUMERIC) as numericVal
I am receiving an error
Conversion failed when converting the varchar value to data type int
while trying to insert data from one table into another. Both have the same table structure (table being inserted is an exact copy of the one used in the Select) and data types on the columns are the same.
INSERT INTO PS_PSOPRDEFN_BA
SELECT *
FROM PSOPRDEFN
Error:
Conversion failed when converting the varchar value '11000_600' to data type int.
The column this is inserting with this value is a varchar(30) in both tables, so I don't know why SQL is trying to convert it to int. Any ideas are appreciated.
When doing inserts, always include the columns:
INSERT INTO PS_PSOPRDEFN_BA ( . . . ) -- column list here
SELECT . . . -- column list here
FROM PSOPRDEFN;
You have a value which is a string which is being assigned to an integer column, and the value cannot be converted.
When doing an insert, the columns are aligned by order in the column list, not by name. So, merely having the same name doesn't mean that the code will work. The tables have to have exactly the same columns defined in the same order with compatible types for your code to work.
A very easy one for someone,
The following insert is giving me the
ORA-01722: invalid number
why?
INSERT INTO CUSTOMER VALUES (1,'MALADY','Claire','27 Smith St Caulfield','0419 853 694');
INSERT INTO CUSTOMER VALUES (2,'GIBSON','Jake','27 Smith St Caulfield','0415 713 598');
INSERT INTO CUSTOMER VALUES (3,'LUU','Barry','5 Jones St Malvern','0413 591 341');
INSERT INTO CUSTOMER VALUES (4,'JONES','Michael','7 Smith St Caulfield','0419 853 694');
INSERT INTO CUSTOMER VALUES (5,'MALADY','Betty','27 Smith St Knox','0418 418 347');
An ORA-01722 error occurs when an attempt is made to convert a character string into a number, and the string cannot be converted into a number.
Without seeing your table definition, it looks like you're trying to convert the numeric sequence at the end of your values list to a number, and the spaces that delimit it are throwing this error. But based on the information you've given us, it could be happening on any field (other than the first one).
Suppose tel_number is defined as NUMBER - then the blank spaces in this provided value cannot be converted into a number:
create table telephone_number (tel_number number);
insert into telephone_number values ('0419 853 694');
The above gives you a
ORA-01722: invalid number
Here's one way to solve it. Remove non-numeric characters then cast it as a number.
cast(regexp_replace('0419 853 694', '[^0-9]+', '') as number)
Well it also can be :
SELECT t.col1, t.col2, ('test' + t.col3) as test_col3
FROM table t;
where for concatenation in oracle is used the operator || not +.
In this case you get : ORA-01722: invalid number ...
This is because:
You executed an SQL statement that tried to convert a string to a
number, but it was unsuccessful.
As explained in:
Oracle/PLSQL: ORA-01722 Error.
To resolve this error:
Only numeric fields or character fields that contain numeric values
can be used in arithmetic operations. Make sure that all expressions
evaluate to numbers.
As this error comes when you are trying to insert non-numeric value into a numeric column in db it seems that your last field might be numeric and you are trying to send it as a string in database. check your last value.
Oracle does automatic String2number conversion, for String column values! However, for the textual comparisons in SQL, the input must be delimited as a String explicitly: The opposite conversion number2String is not performed automatically, not on the SQL-query level.
I had this query:
select max(acc_num) from ACCOUNTS where acc_num between 1001000 and 1001999;
That one presented a problem: Error: ORA-01722: invalid number
I have just surrounded the "numerical" values, to make them 'Strings', just making them explicitly delimited:
select max(acc_num) from ACCOUNTS where acc_num between '1001000' and '1001999';
...and voilà: It returns the expected result.
edit:
And indeed: the col acc_num in my table is defined as String. Although not numerical, the invalid number was reported. And the explicit delimiting of the string-numbers resolved the problem.
On the other hand, Oracle can treat Strings as numbers. So the numerical operations/functions can be applied on the Strings, and these queries work:
select max(string_column) from TABLE;
select string_column from TABLE where string_column between '2' and 'z';
select string_column from TABLE where string_column > '1';
select string_column from TABLE where string_column <= 'b';
In my case the conversion error was in functional based index, that I had created for the table.
The data being inserted was OK. It took me a while to figure out that the actual error came from the buggy index.
Would be nice, if Oracle could have gave more precise error message in this case.
If you do an insert into...select * from...statement, it's easy to get the 'Invalid Number' error as well.
Let's say you have a table called FUND_ACCOUNT that has two columns:
AID_YEAR char(4)
OFFICE_ID char(5)
And let's say that you want to modify the OFFICE_ID to be numeric, but that there are existing rows in the table, and even worse, some of those rows have an OFFICE_ID value of ' ' (blank). In Oracle, you can't modify the datatype of a column if the table has data, and it requires a little trickery to convert a ' ' to a 0. So here's how to do it:
Create a duplicate table: CREATE TABLE FUND_ACCOUNT2 AS SELECT * FROM FUND_ACCOUNT;
Delete all the rows from the original table: DELETE FROM FUND_ACCOUNT;
Once there's no data in the original table, alter the data type of its OFFICE_ID column: ALTER TABLE FUND_ACCOUNT MODIFY (OFFICE_ID number);
But then here's the tricky part. Because some rows contain blank OFFICE_ID values, if you do a simple INSERT INTO FUND_ACCOUNT SELECT * FROM FUND_ACCOUNT2, you'll get the "ORA-01722 Invalid Number" error. In order to convert the ' ' (blank) OFFICE_IDs into 0's, your insert statement will have to look like this:
INSERT INTO FUND_ACCOUNT (AID_YEAR, OFFICE_ID) SELECT AID_YEAR, decode(OFFICE_ID,' ',0,OFFICE_ID) FROM FUND_ACCOUNT2;
I have found that the order of your SQL statement parameters is also important and the order they are instantiated in your code, this worked in my case when using "Oracle Data Provider for .NET, Managed Driver".
var sql = "INSERT INTO table (param1, param2) VALUES (:param1, :param2)";
...
cmd.Parameters.Add(new OracleParameter("param2", Convert.ToInt32("100")));
cmd.Parameters.Add(new OracleParameter("param1", "alpha")); // This should be instantiated above param1.
Param1 was alpha and param2 was numeric, hence the "ORA-01722: invalid number" error message. Although the names clearly shows which parameter it is in the instantiation, the order is important. Make sure you instantiate in the order the SQL is defined.
For me this error was a bit complicated issue.
I was passing a collection of numbers (type t_numbers is table of number index by pls_integer;) to a stored procedure. In the stored proc there was a bug where numbers in this collection were compared to a varchar column
select ... where ... (exists (select null from table (i_coll) ic where ic.column_value = varchar_column))
Oracle should see that ic.column_value is integer so shouldn't be compared directly to varchar but it didn't (or there is trust for conversion routines).
Further complication is that the stored proc has debugging output, but this error came up before sp was executed (no debug output at all).
Furthermore, collections [<empty>] and [0] didn't give the error, but for example [1] errored out.
The ORA-01722 error is pretty straightforward. According to Tom Kyte:
We've attempted to either explicity or implicity convert a character string to a number and it is failing.
However, where the problem is is often not apparent at first. This page helped me to troubleshoot, find, and fix my problem. Hint: look for places where you are explicitly or implicitly converting a string to a number. (I had NVL(number_field, 'string') in my code.)
This happened to me too, but the problem was actually different: file encoding.
The file was correct, but the file encoding was wrong. It was generated by the export utility of SQL Server and I saved it as Unicode.
The file itself looked good in the text editor, but when I opened the *.bad file that the SQL*loader generated with the rejected lines, I saw it had bad characters between every original character. Then I though about the encoding.
I opened the original file with Notepad++ and converted it to ANSI, and everything loaded properly.
In my case it was an end of line problem, I fixed it with dos2unix command.
In my case I was trying to Execute below query, which caused the above error ( Note : cus_id is a NUMBER type column)
select *
from customer a
where a.cus_id IN ('115,116')
As a solution to the caused error, below code fragment(regex) can be used which is added in side IN clause (This is not memory consuming as well)
select *
from customer a
where a.cus_id IN (select regexp_substr (
com_value,
'[^,]+',
1,
level
) value
from (SELECT '115,116' com_value
FROM dual)rws
connect by level <=
length ( com_value ) - length ( replace ( com_value, ',' ) ) + 1)
try this as well, when you have a invalid number error
In this
a.emplid is number and b.emplid is an varchar2 so if you got to convert one of the sides
where to_char(a.emplid)=b.emplid
You can always use TO_NUMBER() function in order to remove this error.This can be included as INSERT INTO employees phone_number values(TO_NUMBER('0419 853 694');
I am getting this Error on Insert statement to AS400 database, using Java with JDBC.
I figured it out, I had a numeric field with length 4 and decimal digits 2, In my insert I was trying to insert 100 in this numeric field which gave this error.
I altered the table and made it numeric with length 9 and decimal digits 2 and the insert worked.
even though the error says "Conversion error", actually its the wrong field length.
I ran in to this issue when a table was updated from 2 digits to 3 for user ID's and the query inserts in to a history table where the history table was not updated to 3 digits for the user id. Used Alter Table to correct the history table and all is well.
alter table "Table Name" ALTER COLUMN "COLUMN NAME" SET DATA TYPE NUMERIC(3)
The error message is not intuitive:
Conversion error on variable or parameter *N (#-302) [IBM][System
iAccess ODBC Driver][DB2 for i5/OS]SQL0012 - Correlation without
qualification occurred for column "columnname" to table "Tablename".
(#12)
I got this error today running the following query:
select *
from mytable
where invoice_date >= '2019-01-01'
Turned out invoice "date" is not a date... it's a decimal that impersonates a date. Poor database design, perhaps, but nonetheless the simple fix was:
select *
from mytable
where invoice_date >= 20190101
My issue was I overlooked the fact that I had single quotes around my parameter place holder. So I was getting a, 6 -- Numeric data that is not valid. error.
So, for example:
select someColumn
From favTable
where someOtherColumn = '?'
command.Parameters.Add("decVal", OleDbType.Decimal, 10).Value = model.someDecVal;
Correcting to:
select someColumn
From favTable
where someOtherColumn = ?
solved my issue.
Looks easy to catch here, but with big queries, this can be easily overlooked. Wasted about an hour on this.
