Summary09283: Short text field not limited to 255 characters when using PostgreSQL
Description

When using a postgresql database, short text fields are created as 'character varying(255)', even when no limit is set on the actual question.

Survey participants are able to submit a response that exceeds this limit without any warning. An error is output to the participant, such as:

Error executing query in dbExecuteAssoc:CDbCommand failed to execute the SQL statement: SQLSTATE[22001]: String data, right truncated: 7 ERROR: value too long for type character varying(255). The SQL statement executed was: UPDATE survey_864954 SET "lastpage"=1, "864954X3X3"='LONG_INPUT' WHERE ID=2

(I truncated the actual response to 'LONG_INPUT').

and the survey administrator receives an email with the subject 'Error saving results'. There is no error actually included, the text at the end just shows:

SQL CODE THAT FAILED:

ERROR MESSAGE:

Steps To Reproduce

Create a survey and add a question of type 'short free text'.
Activate survey
Execute survey, and enter a response in excess of 255 characters
Click next

Additional Information

I believe the issue exists in:

application/helpers/admin/activate_helper.php

on line 293, where the type is set to 'string' for non-MySQL databases. Within the Yii Framework, it appears that this type is cast to varchar(255). Eg, for PostgreSQL, see:

framework/db/schema/pgsql/CPgsqlSchema.php (Line 28)

It appears the issue would affect SQL server as well. Although I have not tested it, it appears that MySQL would behave correctly.

The short text field indeed can only collect 255 characters on Postgres and MSSQL - that is the intended behaviour. Fixed it so that not more than 255 characters can entered on these DB systems.
