Alexander Barkov	69da915160	MCOL-4531 New string-to-decimal conversion implementation ... This change fixes: MCOL-4462 CAST(varchar_expr AS DECIMAL(M,N)) returns a wrong result MCOL-4500 Bit functions processing throws internally trying to cast char into decimal representation MCOL-4532 CAST(AS DECIMAL) returns a garbage for large values Also, this change makes string-to-decimal conversion 5-10 times faster, depending on exact data. Performance implemenent is achieved by the fact that (unlike in the old implementation), the new version does not do any "string" object copying.	2021-02-09 13:02:27 +04:00
Alexander Barkov	b08d719593	A cleanup for MCOL-4064 Make JOIN collation aware ... A non-JOIN condition like `WHERE c1=c2` (with c1 and c2 being columns of the same table) was not collation-aware yet after the main patches for MCOL-4064. Additionally fixing StrFilterCmd::compare*() to address this.	2020-12-08 16:43:07 +04:00
