Read an incident by number

Fetch a specific incident using its human-readable number (for example INC0012345). This is the most common lookup used in integrations and support workflows.

The query filters the incident table using sysparm_query semantics.

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.

-- Query a single incident by incident number
SELECT *
FROM get_table_rows
WITH(
  TableName='incident',
  Query='number=INC0012345'
)

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_SERVICENOW_IN_GATEWAY], '-- Query a single incident by incident number
SELECT *
FROM get_table_rows
WITH(
  TableName=''incident'',
  Query=''number=INC0012345''
)')

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_SERVICENOW_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = '-- Query a single incident by incident number
SELECT *
FROM get_table_rows
WITH(
  TableName=''incident'',
  Query=''number=INC0012345''
)'
EXEC (@MyQuery) AT [LS_TO_SERVICENOW_IN_GATEWAY]
