Question

I’m using db2 export to save data to a CSV file.

Ultimately I need a built a script that will take in a SQL, run it and export it out. I’ve got almost all of it in place, but certain queries cause errors.

Two cases cause errors at the moment:

1 – Using a wildcard. Shell expansion kills this.

Enclosing the whole SQL in ‘ seems to fix that, but what is the best practice? There seem to be some edge cases I haven’t fixed.

2 – I can’t use a string in a where clause:

bash-3.00$ db2 export to /tmp/text of DEL 'select * from SCHEMA.TABLE where COL='STRING''
SQL3022N  An SQL error "-206" occurred while processing the SELECT string in
the Action String parameter.

SQL0206N  "STRING" is not valid in the context where it is used.

Even changing to a specific column to select and removing the ” from the whole SQL doesn’t change it.

Any ideas?

Thanks,

Alex

Answer 1

You have to escape the single quotes in your query string as they close the quotation. Have a look at How to escape single-quotes within single-quoted strings? a solution. But in your case i think it should be enough to use double quotes instead of single quotes for your quotation.
