Sentry Crash Report:

Description Andrius 2014-04-08 16:50:40 UTC

when using substr in a query it returns a blank column

Reproducible: Always

Steps to Reproduce:
1. import text to a table
2. create a query using substr on a field of the table

Actual Results:  
Returned column is blank

Expected Results:  
the query should return the result of the substring (it works in the underlying sqlite3 backend)

Comment 1 Andrius 2014-04-08 16:51:01 UTC

Note: happens on both sqlite3 and mysql backends

Comment 2 Jarosław Staniek 2014-04-09 06:50:39 UTC

Confirmed as a general issue. Set as NORMAL since relatively to other issues it's not above crash.

Kexi queries/parser: make SUBSTR(X, Y [, Z]) built-in SQL function work

This is a first step to make lots of functions work.
https://community.kde.org/Kexi/Plugins/Queries/SQL_Functions#Functions

Details:
- add a few convenience functions to BaseExpr
- N-arg expressions: make token-to-string function support char tokens
- add KexiDBExpr_ArgumentList class ID for N-arg expressions (,,,,)
- FunctionExpr: compute type and validation for SUBSTR()
- parser: also support empty arg list "()" in functions
