Fail to get correct precison and scale of decimal through ODBC SQLDescribeColW()
yingxu9871 opened this issue · comments
Environment:
Clickhouse ODBC driver version: latest one downloaded from https://github.com/ClickHouse/clickhouse-odbc/releases/download/v1.2.1.20220905/clickhouse-odbc-windows.zip
Windows 10
Steps:
- create and insert data by SQL:
CREATE TABLE test_decimal_X
(
id
String,
test_decimal
Decimal(18,10)
)
ENGINE = MergeTree
ORDER BY id
INSERT INTO test_decimal_X VALUES('2',10.12)
-
set up ODBC connection
-
After setting up odbc connection, we use SQLDescribeColW() (written in c++ ) to get precision and scale of decimal, but get result: type=decimal,precision=41,scale=0, 4.
-
The sql I execute is: SELECT T0.
id
ASid
,T0.test_decimal
AStest_decimal
FROMtest_decimal_X
T0. The error I get is : HY000[1] Cannot interpret ‘10.12’ as signed 64-bit integer: Cannot string consumed partially.
Expectation:
Expect to get correct precision and scale of decimal through SQLDescribeColW() .
