In Windows, the DBLIB from Microsoft is used. Functions that return a
|
||||
column name are based on the <literal>dbcolname()</literal> function
|
||||
in DBLIB. DBLIB was developed for SQL Server 6.x where the max
|
||||
identifier length is 30. For this reason, the maximum column length
|
||||
is 30 characters. On platforms where FreeTDS is used (Linux), this is
|
||||
not a problem.
