Syntax

Invoke-ApacheImpala [parameters]

Remarks

The Invoke-ApacheImpala cmdlet allows you to use SQL statements to execute any SQL statement directly. Below is the syntax for a parameterized query:

$query = Invoke-ApacheImpala -Connection $connection -Query 'SELECT * FROM [CData].[Default].Customers WHERE Country=@Country' -Params @{'@Country'='US'}

This cmdlet is also useful for executing stored procedures. Use the EXEC keyword to call a stored procedure:

$query = Invoke-ApacheImpala -Connection $connection -Query 'EXEC SearchSuppliers Country = @Country' -Params @{"US"}

To pass multiple Params parameters, use a semicolon (;) as a delimiter. The code below outlines the structure of an EXEC command with two parameters (param1 and param2):

$query = Invoke-ApacheImpala -Connection $connection -Query 'EXEC MyStoredProc Input1=@param1, Input2=@param2' -Params @{'@param1' = 'value1'; '@param2' = 'value2'}
