SQL Server guide

Read feedbacks with manual pagination

Reads feedback records in batches to overcome API pagination limits. This example demonstrates how to retrieve data month-by-month and combine the results using UNION to get a complete dataset for a longer period.

This approach is necessary when the total number of records exceeds the API's single-request limit, ensuring all data is captured by iterating through date ranges.

Standard SQL query example

This is the base query accepted by the connector. To execute it in SQL Server, you have to pass it to the Data Gateway via a Linked Server. See how to accomplish this using the examples below.

SELECT * INTO #t1 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-01-01', EndTime='2023-02-01');
SELECT * INTO #t2 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-02-01', EndTime='2023-03-01');
SELECT * INTO #t3 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-03-01', EndTime='2023-04-01');
SELECT * INTO #t4 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-04-01', EndTime='2023-05-01');
SELECT * INTO #t5 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-05-01', EndTime='2023-06-01');
SELECT * INTO #t6 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-06-01', EndTime='2023-07-01');
SELECT * INTO #t7 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-07-01', EndTime='2023-08-01');
SELECT * INTO #t8 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-08-01', EndTime='2023-09-01');
SELECT * INTO #t9 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-09-01', EndTime='2023-10-01');
SELECT * INTO #t10 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-10-01', EndTime='2023-11-01');
SELECT * INTO #t11 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-11-01', EndTime='2023-12-01');
SELECT * INTO #t12 FROM Feedbacks WITH(OperatorIds='81565000003048017', StartTime='2023-12-01', EndTime='2024-01-01');

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_ZOHO_SALESIQ_IN_GATEWAY], 'SELECT * INTO #t1 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-01-01'', EndTime=''2023-02-01'');
SELECT * INTO #t2 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-02-01'', EndTime=''2023-03-01'');
SELECT * INTO #t3 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-03-01'', EndTime=''2023-04-01'');
SELECT * INTO #t4 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-04-01'', EndTime=''2023-05-01'');
SELECT * INTO #t5 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-05-01'', EndTime=''2023-06-01'');
SELECT * INTO #t6 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-06-01'', EndTime=''2023-07-01'');

SELECT * INTO #t8 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-08-01'', EndTime=''2023-09-01'');
SELECT * INTO #t9 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-09-01'', EndTime=''2023-10-01'');
SELECT * INTO #t10 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-10-01'', EndTime=''2023-11-01'');

Using EXEC in SQL Server (handling larger SQL text)

The major drawback of OPENQUERY is its inability to incorporate variables within SQL statements. This often leads to the use of cumbersome dynamic SQL (with numerous ticks and escape characters).

Fortunately, starting with SQL 2005 and onwards, you can utilize the EXEC (your_sql) AT [LS_TO_ZOHO_SALESIQ_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * INTO #t1 FROM Feedbacks WITH(OperatorIds=''81565000003048017'', StartTime=''2023-01-01'', EndTime=''2023-02-01'');
