Now ESCAPE in LIKE will accept not only string literal but constant delimited expression. mysql-test/r/func_like.result: Added test for bug# 4200 "Parse error on LIKE ESCAPE with parameter binding" mysql-test/t/func_like.test: Added test for bug# 4200 "Parse error on LIKE ESCAPE with parameter binding" sql/item_cmpfunc.cc: Added support for accepting of constant delimited expression as ESCAPE argument to Item_func_like. sql/item_cmpfunc.h: Now ESCAPE clause in LIKE will accept not only string literal but constant delimited expression. Thus added member to Item_func_like for storing Item corresponding to this expression and changed third argument of cons to be Item* instead of char*. sql/sql_help.cc: Item_func_like now accepts Item* as third argument. sql/sql_yacc.yy: Now ESCAPE clause of LIKE accepts not only string literal but constant delimited expression (the most important case is prepared statement parameter of course).
