I am trying to insert into Table Users from Person table.
However, The first_name column in the person table contains apostrophe in the name (Eg- Rus'sell) which is preventing me from successful insertion. How do I fix this?
INSERT INTO USERS VALUES (SELECT FIRST_NAME,.........FROM PERSON);
INSERT INTO USERS VALUES (SELECT FIRST_NAME,.........FROM PERSON);
First of all, your insert statement is syntactically incorrect. It will raise ORA-00936: missing expression. The correct syntax to insert multiple records from source table is:
INSERT INTO table_name SELECT columns_list FROM source_table;
The VALUES keyword is used to insert a single record into table using following syntax:
INSERT INTO table_name(columns_list) VALUES (expressions_list);
If you already have the value stored in another table, then simple INSERT INTO..SELECT FROM should work without any issues. However, if you are trying to INSERT INTO..VALUES having single quotation marks, then the best way is to use Quoting string literal technique The syntax is q'[...]', where the "[" and "]" characters can be any of the following as long as they do not already appear in the string.
!
[ ]
{ }
( )
< >
You don't have to worry about the single-quotation marks within the string.
create table t(name varchar2(100));
insert into t values (q'[Rus'sell]');
insert into t values (q'[There's a ' quote and here's some more ' ' ']');
select * from t;
NAME
-----------------------------------------------
Rus'sell
There's a ' quote and here's some more ' ' '
I don't think your question is showing the complete details, because I can execute the following statements without any problem:
create table person( first_name varchar2(100));
create table users( first_name varchar2(100));
insert into person values ('Rus''sell');
insert into users select first_name from person;
Apologies for the obscurity if any in the question. The query I was working with was a long insert query with multiple joins.
To sum it was a stored proc where I was doing an insert, for which the data is given by long select query with multiple joins. One of the column is the FIRST_NAME column which had some values with Apostrophe in it (Rus'sell, Sa'm).
The Insert statement values were being generated as below which was causing an 'ORA-00917: missing comma' error.
INSERT INTO TABLE_NAME values (314159,0,'Rus'sell','Parks','...........)
I fixed this by Replacing the column in the select from a single quote to two single quotes, before giving it to the insert statement which basically solved the issue.
REPLACE(FIRST_NAME,'''','''''') AS FIRST_NAME
Hope it helps.
I have a Python script with SQL insert statements that insert parsed data from file to PostgreSQL table. In case data has apostrophes, execution fails. In detail:
<name>RYAZAN'</name>
or
<name>CHYUL'BYU</name>
I found the solution when it is a string -> adding extra ' to apostrophe so it transforms to 'RYAZAN''' or 'CHYUL''BYU' in INSERT statement.
But in case my values are in list (from python script) like city = ["RYAZAN''", "CHYUL''BYU"] Python automatically puts double quotes instead of single quotes. As a result when trying to insert
INSERT INTO City (uuid, name) VALUES (uuid_generate_v4(), unnest(array{city}))
SQL fails with error
ERROR: column "RYAZAN''.." does not exist
because sql reads the double quotes as a column name or whatever. Is there a way to insert ARRAY with values that contain apostrophes?
Try using $$ dollar-quoted strings
CREATE TEMP TABLE t (f TEXT);
INSERT INTO t VALUES ($$<name>CHYUL'BYU</name>$$),
($$<name>RYAZAN'</name>$$);
SELECT * FROM t;
f
------------------------
<name>CHYUL'BYU</name>
<name>RYAZAN'</name>
(2 Zeilen)
There are also many other ways to escape quotes
INSERT INTO t
VALUES (E'\'foo'),('''bar'''),
('"the answer is" -> ''42'''),($$It's "only"" $1.99$$);
SELECT * FROM t;
f
-------------------------
'foo
'bar'
"the answer is" -> '42'
It's "only"" $1.99

I am getting this error
SQL Error: ORA-00928: missing SELECT keyword
00928. 00000 - "missing SELECT keyword"`
when I am trying to insert like this
create table certf
(
certificate_id integer primary key,
certificate_name varchar(100) not null,
certificate_content varchar(300) not null
);
insert into certf (&certificate_id, &certificate_name, &certificate_content);
You are missing values actually:
insert into certf (certificate_id, certificate_name, certificate_content)
values (&certificate_id, &certificate_name, &certificate_content);
Notice that I also added the column list to the insert. This is a best practice.
If those are supposed to be values you're providing as substitution values, then you're missing the values keyword:
insert into certf values (&certificate_id,&certificate_name,&certificate_content);
But you need the string values to be in quotes:
insert into certf values (&certificate_id,'&certificate_name','&certificate_content');
and you should supply the column names too:
insert into certf (certificate_id,certificate_name,certificate_content)
values (&certificate_id,'&certificate_name','&certificate_content');
With you current code the parser is seeing that first list of - possible, but actually invalid in this case - identifiers, i.e column names; because it hasn't seen that values keyword yet. It's treated as something like:
insert into certf (42,some_name,some_content);
And having done that, and when it still doesn't see a values keyword or values list, it's expecting this to be an insert ... select construct instead. You could do it that way:
insert into certf (certificate_id,certificate_name,certificate_content)
select &certificate_id,'&certificate_name','&certificate_content' from dual;
But you aren't doing that. So it doesn't see the select either, and it throws the error you see.
I want to insert multiple rows with a single insert statement.
The following code inserts one row, and works fine:
create temp table mytmptable
(external_id char(10),
int_id integer,
cost_amount decimal(10,2)
) with no log;
insert into mytmptable values
('7662', 232, 297.26);
select * from mytmptable;
I've tried changing the insert to this, but it gives a syntax error:
insert into mytmptable values
('7662', 232, 297.26),
('7662', 232, 297.26);
Is there a way to get it working, or do I need to run many inserts instead?
You could always do something like this:
insert into mytmptable
select *
from (
select '7662', 232, 297.26 from table(set{1})
union all
select '7662', 232, 297.26 from table(set{1})
)
Pretty sure that's standard SQL and would work on Informix (the derived table is necessary for Informix to accept UNION ALL in INSERT .. SELECT statements).
As you found, you can't use multiple lists of values in a single INSERT statement with Informix.
The simplest solution is to use multiple INSERT statements each with a single list of values.
If you're using an API such as ESQL/C and you are concerned about performance, then you can create an INSERT cursor and use that repeatedly. This saves up the inserts until a buffer is full, or you flush or close the cursor:
$ PREPARE p FROM "INSERT INTO mytmptable VALUES(?, ?, ?)";
$ DECLARE c CURSOR FOR p;
$ OPEN c;
while (...there's more data to process...)
{
$PUT c USING :v1, :v2, :v3;
}
$ CLOSE c;
The variables v1, v2, v3 are host variables to hold the string and numbers to be inserted.
(You can optionally use $ FLUSH c; in the loop if you wish.) Because this buffers the values, it is pretty efficient. Of course, you could also simply use $ EXECUTE p USING :v1, :v2, :v3; in the loop; that foregoes the per-row preparation of the statement, too.
If you don't mind writing verbose SQL, you can use the UNION technique suggested by Matt Hamilton, but you will need a FROM clause in each SELECT with Informix. You might specify:
FROM "informix".systables WHERE tabid = 1, or
FROM sysmaster:"informix".sysdual, or
use some other technique to ensure that the SELECT has a FROM clause but only generates one row of data.
In my databases, I have either a table dual with a single row in it, or a synonym dual that is a synonym for sysmaster:"informix".sysdual. You can get away without the "informix". part of those statements if the database is 'normal'; the owner name is crucial if your database is an Informix MODE ANSI database.
In some versions of Infomix you can build a virtual table using the TABLE keyword followed by a value of one of the COLLECTION data types, such as a LIST collection. In your case, use a LIST of values of Unnamed Row type using the ROW(...) constructor syntax.
Creating a TABLE from COLLECTION value

ROW(...) construction syntax, for literals of Unnamed Row data type
http://www.ibm.com/support/knowledgecenter/SSGU8G_11.50.0/com.ibm.sqlr.doc/ids_sqr_136.htm
Example:
select *
from TABLE(LIST{
ROW('7662', 232, 297.26),
ROW('7662', 232, 297.26)
}) T(external_id, int_id, cost_amount)
into temp mytmptable with no log
In the above, the data types are implied by the value, but when needed you can explicitly cast each value to the desired data type in the row constructor, like so:
ROW('7662'::char(10), 232::integer, 297.26::decimal(10,2))
You can also insert multiple rows by storing the values in an external file and executing the following statement in dbaccess:
LOAD FROM "externalfile" INSERT INTO mytmptable;
However, the values would have to be DELIMITED by a pipe "|" symbol, or whatever you set the DBDELIMITER environment variable to be.
If you're using the pipe delimiter, the data in your external file would look like:
7662|232|297.26|
7663|233|297.27|
...
NOTE that the data in the external file must be properly formatted or able to be converted to successfully be inserted into each mytmptable.column datatype.
Here is a simple solution fro bulk insert with SELECT part solving the rest
INSERT INTO cccmte_pp
( cmte, pref, nro, eje, id_tri, id_cuo, fecha, vto1, vto2, id_tit, id_suj, id_bie, id_gru )
SELECT * FROM TABLE (MULTISET {
row('RC', 4, 10, 2020, 1, 5, MDY(05,20,2020), MDY(05,20,2020),MDY(05,27,2020),101, 1, 96, 1 ),
row('RC', 4, 11, 2020, 1, 5, MDY(05,20,2020), MDY(05,20,2020),MDY(05,27,2020),101, 1, 96, 1 ) })
AS t( cmte, pref, nro, eje, id_tri, id_cuo, fecha, vto1, vto2, id_tit, id_suj, id_bie, id_gru )
;
How would I write a loop that has a select in the “in” clause of the loop that selects a col of type varchar(10), but then inserts those values in a col that wants them to be varchar(9)? Basically I’m trying to “typecast” from one precision to another, if that makes any sense. Example:
FOR V_TEN IN (SELECT THIS_IS_VARCHAR_TEN FROM TABLE WHERE SOMETHING=’VALUE’)
LOOP
INSERT INTO OTHER_TABLE
(THIS_IS_VARCHAR_NINE)
VALUES
(V_TEN);
END LOOP;
The error is that the column types aren’t the same. I’ve tried looking at to_char() and cast() but neither seem to be what I want. I realize there is a loss of precision here and am okay with that, since I actually know that the values in the varchar(10) column are always going to be 9 chars.
You are looking for the SUBSTR function.
Also, do not use PL/SQL for this, plain SQL will do and be faster.
INSERT INTO OTHER_TABLE
SELECT OTHER_COLUMN, SUBSTR(THIS_IS_VARCHAR_TEN,1,9)
FROM TABLE WHERE SOMETHING=’VALUE’;
And if there are really no values longer than nine character, you do not even need to call the substr function (it will be converted automatically, and raise an error if too long).
since I actually know that the values
in the varchar(10) column are always
going to be 9 chars.
If that's true, then you don't even need to use SUBSTR as others have been suggesting.
I believe the reason that you're getting an error is that you are trying to insert the value of V_TEN. When you use a construct like FOR x IN (SELECT ...) LOOP, x is implicitly declared as a record type. In your case, it's a record with only one field, but you still can't use it directly as a scalar type.
You just need to reference the field of the record by name in your insert.
FOR V_TEN IN (SELECT THIS_IS_VARCHAR_TEN FROM TABLE WHERE SOMETHING=’VALUE’)
LOOP
INSERT INTO OTHER_TABLE
(THIS_IS_VARCHAR_NINE)
VALUES
(V_TEN.THIS_IS_VARCHAR_TEN);
END LOOP;
In any case, as Thilo pointed out, there's no reason to do this in an explicit loop at all. Just write it as a single INSERT ... SELECT.
Use:
FOR V_TEN IN (SELECT SUBSTR(t.this_is_varchar_ten, 1, 9)
FROM TABLE t
WHERE t.something = 'VALUE')
LOOP
INSERT INTO OTHER_TABLE
(THIS_IS_VARCHAR_NINE)
VALUES
(V_TEN);
END LOOP;
Use the SUBSTR function to substring the VARCHAR(10) data so it is returned as VARCHAR(9)
