Info

TSQL Commands• [server], [database], [owner] and [object] refer to those components of the tablereference as in SQLServer.The component names have synonyms as follows:• server: ser• database: dat, schema, or sch• owner: own• object: obj, table, or tabYou can also supply alternatives to be used if components are missing. For example:[dat|ser|own] means use the database component if present, else the server if present, elsethe owner if present. For example: [dat|ser|own].[obj] will convert A.B.C.D to B.D andA..C.D to A.DAnd you can have leading and trailing non-letters just after the "[" or just before the "]" whichare only inserted into the generated name if the component expression yields a non-emptyresult. For example: [dat|ser.][obj] will convert A.B.C.D to B.D, A..C.D to A.D butC.D to D (not .D)Note that the non-letters must not go inside the |..|, they must only appear at the startand/or end of the string.26 Caché Transact-SQL (TSQL) Migration Guide
