UPDATE JOIN syntax problem |
Tue, Jun 13 2006 12:48 AM | Permanent Link |
Jeff Cook | Hi
Having a little trouble with this SQL with DBISAM v3.30:- START TRANSACTION ; SELECT TransNo, TransType INTO MEMORY Temp1 FROM TenantTrans WHERE TenantCode = '0072' ; ALTER TABLE MEMORY Temp1 ADD PRIMARY KEY (TransNo) ; UPDATE TransReg R SET PreDeletion = T1.TransType, TransType = 'Deleted', Changed = True FROM TransReg R JOIN MEMORY Temp1 T1 ON (T1.TransNo = R.TransNo) ; DROP TABLE MEMORY Temp1 ; COMMIT FLUSH ================ I'm getting error 11949 "Invalid column name TransNo or table correlation name 'R' specified in WHERE or JOIN clause." Can't work out the correct syntax - the column name TransNo is definitely correct. TIA Jeff -- Jeff Cook Aspect Systems Ltd Phone: +64-9-424 5388 Skype: jeffcooknz www.aspect.co.nz |

You can not use ALTER TABLE inside transactions, even in v4. Eduardo |

That's odd - it seems to be executing that bit OK and only fails on the next statement Actually, the script I started with had more statements that ran successfully between the ALTER and the UPDATE that is failing. :-\ And I just removed the START TRANSACTION and the COMMIT and the problem remains.

Much head scratching going on here! I changed the MEMORY table to a real one so I can run the steps one at a time and each step seems OK ... AAAAAAAAAH! Enlightenment! It was the next step that was generating the error. Dummy! I must have got it fixed in my brain that it was the UPDATE statement that was causing the problem - but it was the next statement and it was indeed an invalid correlation name. Thanks for your help (and patience) Tim and Eduardo. Will ElevateDB have error messages pointing to the statement in a script that is generating the error? Hope so!
