powershell - Concat invoke-SqlCmd query string does not work -

-

how can concat list of parameter or string of parameter (better) sql query? below not work.

$parameters = @("-serverinstance `"mymachine\sqlexpress`"", "-database %targetdbname%", "-username %sqlusername%", "-password %sqlpassword%") $row = invoke-sqlcmd -query "select field table;" $parameters

i want execute later multiple queries same connection parameters , usefull reuse them in string can add query string.

you on right track. sounds looking splatting.

splatting method of passing collection of parameter values command unit.

i don't use invoke-sqlcmd should work this:

$parameters = @{     serverinstance = "mymachine\sqlexpress"     database = "targetdbname"     username = "sqlusername"     password = "sqlpassword"     query = "select field table;" }  $row = invoke-sqlcmd @parameters

collect parameters hashtable , splat cmdlet. if wanted use parameter set again later, make small changes, easy referencing name/value pair of hashtable.

$parameters.query = "select field differenttable;" $anotherrow = invoke-sqlcmd @parameters
