CAST truncates without warning
Started by mike galmost 22 years ago2 messagesgeneral
Hello,
If a column, data type text, with 22 characters of data, is then CAST(column_name as varchar(20)) shouldn't a warning or error be generated?
If the source is a variable defined as text instead of directly from a table, using plpsql, would that matter?

No. This is per SQL spec.
You will get a warning if you assign the value to a varchar(20) table
column *without* any explicit cast. This is also per SQL spec.
