query raise SIGSEGV in not main thread if connection lost (Linux, Firebird)

Hi. Use Zeos r7867, Lazarus 2.2.2, FPC 3.2.2, Ubuntu 16.04 32bit, Firebird 3.0. Testing reconnection after connection lost. Found, that if TZReadOnlyQuery.Open executed in different (not main) thread on connection lost raises SIGSEGV, so connection can not be reopened. Seems, connection object is br...

Re: Firebird stored procedure returning void dataset raise exception

Solved both problem by changing TZStoredProc to TZReadOnlyQuery with SQL:

Code: Select all

SELECT * FROM VOID_TEST_PROC(:P0)
Works both with FB 3 and 2.5

Re: problem with stored procedure returning 2 datasets (MySQL 8)

Solved by changing NextRecordSet (aka NextResultSet) to SetResultSet(1) for second DS.
"Open" does not clean FActiveResultIndex, so it stores from previous call. Have to use absolute value via SetResultSet.

Re: Postgres batch update can not work

Solved by replacing SQL from UPDATE BATCH_TEST_TABLE SET VAL_FIELD = :P0 WHERE VAL_FIELD = :P1 to UPDATE batch_test_table SET val_field = "CAST"(r.c0 as integer) FROM (SELECT :p0 as c0, :p1 as c1 ) r WHERE val_field = "CAST"(r.c1 as integer) Version with CTE WITH r(c0 ,c1 ) AS (S...

Re: Batch inserts with Firebird 3

I can't connect to Firebird server (version WI-V6.3.7.33374 Firebird 3.0) with FB 2.5 client library (version 2.5.9.27139). Do not know, why. Keep using FBCLIENT.DLL version 3.0.7.33374. But your result looks even more strange. As I understand tracing TZAbstractFirebirdStatement.Prepare, Zeos device...

Re: Firebird stored procedure returning void dataset raise exception

Thanks. Docs say so, but it does not work in Delphi 7. Not sure, than it's really important. Check for myself.

Postgres batch update can not work

Batch update can not work with Postgres - function unnest can not be used in WHERE clause.

Generated query:

Code: Select all

UPDATE BATCH_TEST_TABLE SET VAL_FIELD = unnest($1::int4[]) WHERE VAL_FIELD = unnest($2::int4[])
Table DDL:

Code: Select all

CREATE TABLE BATCH_TEST_TABLE (
    VAL_FIELD  INTEGER
);

problem with stored procedure returning 2 datasets (MySQL 8)

Second dataset is readable in first call of procedure only.

Procedure DDL:

Code: Select all

CREATE PROCEDURE `TwoDSTest`()
BEGIN
    SELECT * FROM (VALUES ROW(1.1, 1.2), ROW(2.1, 2.2)) as T(f1, f2);
    SELECT * FROM (VALUES ROW(3), ROW(4), ROW(5)) as T2(f3);
END
