Desktop error where datetime and timestamp insmatch after removing [Implementation="2.0"]

[rishabjain237]

Hi #community,
I have a table in Big query which has around 130 Million rows in Big query(The table has a datetime column). so I have setup a incremental refresh to reduce the refresh time on power BI services. since september first week I have been facing the ReadChunkyRetires error in serivces so after searching on this platform I came to know about the drivers issue.
As per the suggestions given in the thread I remove the [Implementation="2.0"]  from the GoogleBigQuery.Database([Implementation="2.0"]) part of the source but, when I applied the changes I got an error in the desktop saying - 
google_search_console
OLE DB or ODBC error: [DataSource.Error] ODBC: ERROR [42000]
[Microsoft][BigQuery] (70) Invalid query: No matching signature
for operator >= for argument types: DATETIME, TIMESTAMP
Signature: T1 >= T1 Unable to find common supertype for
templated argument <T1> Input types for <T1>: {TIMESTAMP,
DATETIME} at [13:7].

Both the source data and parameters used for incremental refresh are datetime type.
This error isn't appearing when I use the [Implementation="2.0"]  in the M code.
Please suggest on how to resolve this issue.

Thanks,
Regards,
Rishab Jain

Hi @rishabjain237  - Convert your parameter type to match the table’s column type. If your column is DATETIME, ensure the parameter is passed as DATETIME, not TIMESTAMP.

Change your M query to explicitly cast the parameter as DATETIME

let
StartDateTime = DateTime.ToText(IncrementalStartDate, "yyyy-MM-dd HH:mm:ss"),
Source = Odbc.Query("dsn=BigQueryDSN",
"SELECT * FROM `your_project.your_dataset.your_table`
WHERE DateTimeColumn >= DATETIME('" & StartDateTime & "')")
in
Source

This way, the IncrementalStartDate is converted to string in the correct format and passed as a DATETIME literal in the query.Once you handle the type correctly, removing [Implementation="2.0"] will work because the query no longer fails on type mismatch.

Hope this helps.
