REPLACE and charset of third parameter
--
Key: CORE-5919
URL: http://tracker.firebirdsql.org/browse/CORE-5919
Project: Firebird Core
Issue Type: Bug
Affects Versions: 3.0.4
Reporter: Kovalenko Dmitry
Connection charset: win1251
CREATE TABLE TEST_MODIFY_ROW (
TEST_IDT_TEST_ID NOT NULL /* T_TEST_ID = BIGINT */,
COL_VARCHAR_10 T_VARCHAR_10 /* T_VARCHAR_10 = VARCHAR(10), CHARSET:
WIN1251 */,
);
For query1
SELECT "r"."TEST_ID", "r"."COL_VARCHAR_10" FROM "TEST_MODIFY_ROW" AS "r"
WHERE (POSITION(REPLACE("r"."COL_VARCHAR_10", 'ABC', :__vv_0),
"r"."COL_VARCHAR_10") > 0) AND ("r"."TEST_ID" = :__8__locals1_testID_1)
Server returns that "__vv_0" parameter has NON OCTETS charset.
For query2:
SELECT "r"."TEST_ID", "r"."COL_VARCHAR_10" FROM "TEST_MODIFY_ROW" AS "r"
WHERE (POSITION(REPLACE("r"."COL_VARCHAR_10", 'ABC'||x'00'||'123', :__vv_0),
"r"."COL_VARCHAR_10") > 0) AND ("r"."TEST_ID" = :__8__locals1_testID_1)
Server returns that "__vv_0" parameter has OCTETS charset.
Difference of these queries in second parameter of REPLACE: 'ABC' and
'ABC'||x'00'||'123'.
For me - in second query parameter "__vv_0" should has NON OCTETS charset.
Could anybody confirm this behaviour and explain the reason?
