ruowan opened a new issue, #1569: URL: https://github.com/apache/arrow-adbc/issues/1569
### What happened? Snowflake getSchemaTable, it throw KeyNotFoundException exception when calling ConvertArrowSchema. You could reproduce this error by executing the query “SELECT * FROM PUBLIC.TEST_ALLTYPE_EMPTY” and `reader.GetSchemaTable()`. I also did some investigation. The exception is throwed from this line: https://github.com/apache/arrow-adbc/blob/fa8498f39fa69e01cdf2c5557e15cd4e6dc0fac2/csharp/src/Client/SchemaConverter.cs#L69. When the type is float, actually the metadata doesn’t contain precision and scale property, leading to the exception. Error call stack: at System.ThrowHelper.ThrowKeyNotFoundException() at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at Apache.Arrow.Adbc.Client.SchemaConverter.ConvertArrowSchema(Schema schema, AdbcStatement adbcStatement, DecimalBehavior decimalBehavior) in Apache.Arrow.Adbc.Client\SchemaConverter.cs:line 41 at Microsoft.Connectors.Snowflake.SnowflakeV2DataReader.GetSchemaTable() in D:\Repos\HybridDataIS\Source\SideBySideConnectors\SnowflakeV2\1.0.0.0\Source\SnowflakeV2DataReader.cs:line 152 ### How can we reproduce the bug? executing the query “SELECT * FROM PUBLIC.TEST_ALLTYPE_EMPTY” and `reader.GetSchemaTable()`. ### Environment/Setup _No response_ -- This is an automated message from the Apache Git Service.
