| | | | | | | | | | | | | | if it has one or more empty string inputs. This fixes a bug introduced by [c6da39115d3e2b0f] on 2019-03-26 (version 3.28.0) and reported by [forum/forumpost/bf8f43aa522c2299|forum post bf8f43aa522c2299].

| |\ | | | | | | | | | | | | | | | | | | | | | | | | 3.46.0 release. (1) Allow arbitrary expressions in the second argument to the RAISE() function. (2) Performance optimization to the OP_OpenRead and OP_OpenWrite bytecode operators. (3) Allow FTS5 tables to be dropped even if the associated tokenizer is not available. (4) Performance optimizations in FTS5. (5) Generate better bytecode to improve performance of ONEROW scans. FossilOrigin-Name: 1e5385ffc30743412ade1536583504eec36790cac5355042aa1e12d8d2271d1f
