For table name A maximum of 32 characters is used.
I wish to know if this be for Field name also.
Tables are named according to the following rules:
1. If a label immediately precedes a load or select statement the label will be used as table name. The label must be followed by a colon .
2. If no label is given, the filename or table name immediately following the keyword from in the load or select statement is used. A maximum of 32 characters is used. For filenames the extension isskipped.
IMHO there is no theoretical limit to the length of the string part of a field value.
However, I ran into trouble more than once when creating text keys longer than, say, 80000 characters. So my advice would be to never exaggerate and switch to AutoNumber/AutoHashXXX translations as soon as possible. Especially whenever the cardinality of your field is high.
Problems with this part of the QlikView kitchen are extremely difficult to trace.
