I came across a statement like this while tracking down a separate issue and at first didn’t think much of it since it wasn’t related to the problem at hand. However, when running my process through the debugger I noticed a SQL error which caught my attention.<\/p>\n
<code>UPDATE dbo.shipperDetail\nSET contractId = (SELECT max(docId) \n\t\t\tFROM dbo.orderHeader\n\t\t\tWHERE dbo.shipperDetail.catalogNo = dbo.orderHeader.catalogNo\n\t\t\tAND dbo.shipperDetail.partNo = dbo.orderHeader.partNo\n\t\t\tAND dbo.shipperDetail.customerNo = dbo.orderHeader.customerNo\n\t\t\tand dbo.orderHeader.status = 'A')\nFROM dbo.shipper\nWHERE<strong> dbo.shipperDetail =<\/strong> :al_ship_id -- what column?\nAND dbo.shipper.shipperNo = dbo.shipperDetail.shipperNo\nAND dbo.shipper.shipFlag = 'N'\nUSING SQLCA;\nCOMMIT;<\/code><\/pre>\nNotice the WHERE clause.<\/p>\n
Since SQLCA.SQLCode was not checked after the initial UPDATE statement, the error was not caught. This was in a production application for several years. Remember that only imbedded SELECT statements are validated when you ‘compile’ or save a script.<\/p>\n\n\n
