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

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

git - How to list all releases of public repository with GitHub API V3 -

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
