Array is returned instead of hashtable - powershell

Question

I have following powershell script:
$reportsFolder = $PSScriptRoot;
$reportServerDbInstance = "localhost";
$dbName = "dbname";
function Execute-Query{
Param(
[parameter(position=0)]
$query,
[parameter(position=1)]
$execDb
)
Invoke-Sqlcmd -Query $query -ServerInstance $reportServerDbInstance -Database $execDb -ErrorAction 'Stop'
}
function Test-ReportQuery($query, $execDb) {
Execute-Query -query $query -execDb $execDb
}
function Test-ReportQueries($reportName, $queries) {
foreach($q in $queries.GetEnumerator()) {
try {
Test-ReportQuery -query $q.Value -execDb $dbName
}
catch {
$errorMsg = "Dataset `"$($q.Name)`" for report `"$reportName`" failed. Check the query";
Write-Error $errorMsg
Write-Error $q.Value
Write-Error $_;
}
}
}
function Prepare-QueriesFromReportForTest ($folder, $name)
{
[OutputType([System.Collections.Hashtable])]
$tmpReportString = gc $(Join-Path $folder "$name.rdl");
[xml]$report = $tmpReportString;
foreach($ds in $report.Report.DataSources.DataSource) {
if ($ds.DataSourceReference -ne "rdb_custom") {
Write-Host "Report $name skipped as datasource is not rdb_custom";
return;
}
}
$paramsFromReport = $report.Report.ReportParameters;
$params = #{}
$tmpParams = #{}
foreach ($p in $paramsFromReport.ReportParameter ) {
$value = "''";
if ($p.DataType -eq "DateTime" ) {
$value = "GETDATE()";
}
if ($p.DataType -eq "Boolean") {
continue;
}
if ($p.DataType -eq "Float" ) {
$value = "0";
}
if ($p.DataType -eq "Integer" ) {
$value = "0";
}
9009
$params.add($p.Name, $value);
$tmpParams.add($p.Name, $value);
}
$testQueries = $null;
$testQueries = #{};
foreach($q in $report.Report.DataSets.DataSet) {
if ($q.Query -eq $null) {
continue;
}
#getting the dataset parameters that <> to report parameters
foreach($p in $q.Query.QueryParameters.QueryParameter) {
foreach($p1 in $tmpParams.GetEnumerator()) {
if (($p.Value -eq "=Parameters!$($p1.Name).Value".Replace("#","")) -and ($p.Name -ne "#$($p1.Name)") ) {
$params.add($p.Name.Replace("#",""), $p1.Value);
}
}
}
$query = $q.Query.CommandText.Trim().Replace(";","").ToLower();
foreach ($param in $params.GetEnumerator()) {
$query = $query.Replace("#$($param.Name.ToLower())", $param.Value );
}
if ($query.Substring(0,6).ToLower() -eq "select") {
$testQueries.add($q.Name, "SELECT * FROM (SELECT TOP(0) " + $query.Substring(6, $query.Length -6) + ") a");
}
}
$testQueries
#return $testQueries;
}
Get-ChildItem $reportsFolder -Filter Water_Queue_Detail_Report.rdl |
Foreach-Object {
$fileName = $_.BaseName;
Write-Host "Testing $fileName report";
$queriesToTest = Prepare-QueriesFromReportForTest -folder $reportsFolder -name $fileName
if ($queriesToTest -ne $null) {
Test-ReportQueries -reportName $fileName -queries $queriesToTest;
}
}
When I am debugging the Prepare-QueriesFromReportForTest function just before it finishes it has proper values in the hash table:
However the variable $queriesToTest getting some weird values (some integer 9009) + expected value:
I checked the types of both objects and I see that in the function the object is hash, but the function returns array.
What's wrong?

Answer 1

The Prepare-QueriesFromReportForTest function has a lone line containing only number 9009 in the foreach loop. Remove that:
if ($p.DataType -eq "Integer" ) {
$value = "0";
}
9009
$params.add($p.Name, $value);
$tmpParams.add($p.Name, $value);
