I want to perform insert operation on a list of objects.
My insert query looks like below
insert into table name (#[flowVars['columnNames']]) values (#[flowVars['values']])
#[flowVars['columnNames'] contains the comma separated columnNames like col1,col2
#[flowVars['values'] contains #[payload.?val1], #[payload.?val2]
I get the below error.
Invalid column name '#P0'. (com.microsoft.sqlserver.jdbc.SQLServerException)
How can i solve this issue?
I can suggest you debug and check whether you have correct value has been set for flowVars['columnNames'] and flowVars['values'], also you can put it in logger to see its value in log. Then check if the output from the above is matching with the column name required for this insert operation.
IMHO, the Query above is not suitable for the Parameterized query. Because the constructed query will be incorrectly interpreted by Mule. It might be constructed like this: insert into tableName ('col1,col2') values ('\'val1\',\'val2\'')
Therefore, I suggest to change the Query Type to: Dynamic.

I'm trying to write the value of a parameter in Anylogic into a specific cell of a Database table. The parameter is declared in my main and gets its value through a specific calculation in function. Now I want to store the calculated value in the Database table.
I tried using the
INSERT INTO query (executeStatement("INSERT INTO eu (country, capital) VALUES ('Croatia', 'Zagreb')"); --> example from help)
…but I'm not able to use the specific parameter in the query/as a VALUE. I can only write direct input (like 'Croatia'), but not the parameter. At the end I want the table to get the current value from the parameter and insert the value in the table.
I found an Insert connectivity tool in the help function, but unfortunately it's only available in the professional edition.
Does anyone have an idea how to handle this?
Thank you and have a great weekend!
I don't know if I fully understood what you need but if what you want to do is simply insert values into a table, then what you've done inside your "executeStatement" is actually enough:
INSERT INTO eu (country, capital) VALUES ('Croatia', 'Zagreb')
If what you mean by "specific cell" is actually replacing the content of an existing field in a given row, you want to use UPDATE instead:
UPDATE eu SET country='New country', capital='New capital' WHERE <some criteria matching targeted row>
WARNING: don't forget the WHERE statement or every row of your table will be clobbered with these same new values.
And if what you want to do is inserting one or more new rows filled with something that already exists in the database, then you can construct your dataset directly from a SELECT query:
INSERT INTO eu (country, capital)
SELECT country_field, capital_field
FROM some_table
WHERE some_criteria
The SELECT query following the UPDATE statement can be absolutely anything. It may also refer to the same table if needed. The only requirement is to form rows that have the same structure and same type (at least compatible) than the targeted fields.
You need to adjust your String that defines the SQL statement.
Instead of
"INSERT INTO eu (country, capital) VALUES ('Croatia', 'Zagreb')"
you write
"INSERT INTO eu (country, capital) VALUES ('"+myParam1+", '"+myParam2+"')"
Assuming you have 2 params of type String that hold string text.
Your dbase column type must match the parameter (or variable) type you want to write
Be VERY careful with the ' and " signs as above
Is there any generic command or syntax in SQL to allow one to have multiple values in a where statement without using OR?
OR just gets tedious when you have many values to choose from and you only want say half of them.
I want to return only columns that contain certain values. I am using Cache SQL, but as I said, a generic syntax might be helpful as well because most people are unfamiliar with Cache SQL. Thanks!
You should use IN:
... where column_name in ('val1', 'val2', ...);
Use the 'IN' clause.
SELECT * FROM product WHERE productid IN (1,2,3)
I believe you are looking for the IN clause.
Determines whether a specified value matches any value in a subquery or a list.
I have 2 sqlite databases, and I'm trying to insert data from one database to another. For example, "db-1.sqlite" has a table '1table' with 2 columns ('name', 'state'). Also, "db-2.sqlite" has a table '2table' with 2 columns ('name', 'url'). Both tables contain a list of 'name' values that are mostly common with each other but randomized, so the id of each row does not match.
I want to insert the values for the 'url' column into the db-1's table, but I want to make sure each url value goes to its corresponding 'name' value.
So far, I have done this:
> sqlite3 db-1.sqlite
sqlite> alter table 1table add column url;
sqlite> attach database 'db-2.sqlite' as db2;
Now, the part I'm not sure about:
sqlite> insert into 1table(url) select db2.2table.url from db2.2table where 1table.name==db2.2table.name
If you look at what I wrote above, you can tell what I'm trying to accomplish, but it is incorrect. If I can get any help on the matter, I'd be very grateful!!
The equality comparison operator in SQL is =, not ==.
Also, I suspect that you should be updating 1table, rather then inserting in it.
Finally, your table names start with digits, so you need to escape them.
This SQL should work better:
update `1table`
set url = (select db2.`2table`.url
from db2.`2table`
where `1table`.name = db2.`2table`.name);
I have a table with 2 columns. I want to provide the 1st columns value but use a select statement to query another table to figure out the value that will go in the 2nd column of the first table.
Heres what I came up with but I know is wrong..
INSERT INTO VehicleModels_VehicleSubModels (VehicleModelId, VehicleSubModelYearId)
(SELECT #ModelId, VehicleSubModelYearId
FROM VehicleSubYearIntermediate
WHERE SubModelId=#SubModelId
AND YearId=#YearId)
Essentially I want to provide the value for VehicleModelId through #ModelId, but it won't let me use it outside of the select statement.
Try removing the brackets around the SELECT, as presumbably you're seeing an incorrect syntax error?
INSERT INTO VehicleModels_VehicleSubModels (VehicleModelId, VehicleSubModelYearId)
SELECT #ModelId,VehicleSubModelYearId
FROM VehicleSubYearIntermediate
WHERE SubModelId=#SubModelId
AND YearId=#YearId
I created a table with this schema using sqlite3:
CREATE TABLE monitored_files (file_id INTEGER PRIMARY KEY,file_name VARCHAR(32767),original_relative_dir_path VARCHAR(32767),backupped_relative_dir_path VARCHAR(32767),directory_id INTEGER);
now, I would like to get all the records where original_relative_dir_path is exactly equal to '.', without 's. What I did is this:
select * from monitored_files where original_relative_dir_path='.';
The result is no records even if in the table I have just this record:
1|'P9040479.JPG'|'.'|'.'|1
I read on the web and I see no mistakes in my syntax... I also tried using LIKE '.', but still no results. I'm not an expert of SQL so maybe you can see something wrong?
Thanks!
I see no problem with the statement.
I created the table that you described.
Did an INSERT with the same values that you provided.
And did the query, and also queried without a where clause.
No problems encountered, so I suspect that when you execute your selection, you may not be connected to the correct database.
