Dear Sir,
I have just started to program in pgtcl.I have to write a procedure for
connecting to a table and fetching records and inserting them.What should
I do to catch the error conditions?The postmaster runs in a separate
terminal and Tcl in another one.The errors may be non existing table
name,field name or errors like query fetching many rows as result.Please
give me a solution for this problem.Thanking you.

Yours truly,
Senthil J
