Converts a value to CLOB data type.
This is a convertible function resolved by USoft but NOT supported on MS Sql Server, where you must use CONVERT.
Large strings (>32K) returned by component methods are truncated when used in other SQL statements. If the method call is called directly within an INVOKE statement, for example:
then there is no problem returning the large string. But as soon as the call is incorporated in a SQL statement, the value will be silently truncated to 32K, the USoft limit for long strings. For example:
You can use the TO_CLOB() function to return the long string correctly without it being truncated.
The TO_CLOB() function must be positioned directly around the method call, otherwise truncation might occur before the TO_CLOB() function can do the conversion. For example, the following statement still truncates the value:
To ensure that no truncation occurs, the TO_CLOB() function must be positioned directly around the method call:
