Actually you do need quotes, otherwise the substitution will resolve to

strTblName := TB_B4000;

which in the absence of a variable or (presumably) function named TB_B4000 will give an 'identifier must be declared' error.

I was also puzzled by the Arto's comment, that assigning the value 'TB_B4000' (in single quotes) to a 1-character CHAR string will give the first single quote only. No it won't.

Also (to the OP), why CHAR? I thought that had been rightly banned throughout the civilized galaxy? You'll be using VARRAYs next ;)

Oh and there is no SQL in your example. Received on Sat Apr 28 2007 - 04:11:49 CDT
