VARCHAR of insufficient length used for set bind of decfloat to varchar
-----------------------------------------------------------------------
Key: CORE-6206
URL: http://tracker.firebirdsql.org/browse/CORE-6206
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 4.0 Beta 1
Environment: Firebird-4.0.0.1689-0_x64 windows 10
Reporter: Mark Rotteveel
The bind for a decfloat(34) to varchar is two (2) characters too short to show
a maximum width value:
SQL> set sqlda_display on;
SQL> set bind of decfloat to varchar;
SQL> select -9.999999999999999999999999999999999E+6144 from rdb$database;
INPUT message field count: 0
OUTPUT message field count: 1
01: sqltype: 448 VARYING scale: 0 subtype: 0 len: 40 charset: 0 NONE
: name: CONSTANT alias: CONSTANT
: table: owner:
CONSTANT
========================================
Statement failed, SQLSTATE = 22001
Dynamic SQL Error
-SQL error code = -303
-arithmetic exception, numeric overflow, or string truncation
-string right truncation
-expected length 40, actual 42
Using set bind of decfloat to char works fine and has the required length of 42:
SQL> set bind of decfloat to char;
SQL> select -9.999999999999999999999999999999999E+6144 from rdb$database;
INPUT message field count: 0
OUTPUT message field count: 1
01: sqltype: 452 TEXT scale: 0 subtype: 0 len: 42 charset: 0 NONE
: name: CONSTANT alias: CONSTANT
: table: owner:
CONSTANT
==========================================
-9.999999999999999999999999999999999E+6144
