Powershell Invoke-Sqlcmd doesn't capture all verbose output

I created following powershell (v2) script to execute query on target database and build another query/queries to be run:

$sql = @"
DECLARE @Tables CURSOR;
DECLARE @TableName NVARCHAR(200);

BEGIN
    SET @Tables = CURSOR FOR
    SELECT TABLE_NAME
    FROM test.INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE='BASE TABLE' 
    AND TABLE_NAME LIKE 'x%'

    OPEN @Tables 
    FETCH NEXT FROM @Tables 
    INTO @TableName
    WHILE @@FETCH_STATUS = 0
    BEGIN
        PRINT 'SELECT TOP 1 * FROM test.dbo.' + @TableName
        FETCH NEXT FROM @Tables 
        INTO @TableName 
    END; 

    CLOSE @Tables ;
    DEALLOCATE @Tables;
END;
"@
$ps = [PowerShell]::Create()
$ps.AddCommand("Invoke-Sqlcmd").AddParameter("Query", $sql).AddParameter("Verbose")
$ps.Invoke()

$sqlOutput = $ps.Streams.Verbose
$sqlOutputToRun = $nul
$sqlOutput | foreach {
    $sqlOutputToRun += ($_.ToString() + "`n")
}
$sqlOutputToRun = @"
$sqlOutputToRun
"@

$sqlOutputToRun

In the end of script I am printing queries that have to be executed, but unfortunately variable $sqlOutputToRun contains only about 3/4 expected output. I suppose that output is somehow cut because of the size, but I am not sure how I can extend it.

Do you know what is missing?

And once you dump the print statements in favor of a resultset, you can dump the cursor too, and just run a simple query like:

    select 'SELECT TOP (1) * FROM '+ quotename(table_catalog) + '.' + quotename(table_schema) + '.' + quotename(table_name)
    FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE='BASE TABLE' 
    AND TABLE_NAME LIKE 'x%'

so in Powershell:

$sql = @"
        select 'SELECT TOP (1) * FROM '+ quotename(table_catalog) + '.' + quotename(table_schema) + '.' + quotename(table_name)
        FROM INFORMATION_SCHEMA.TABLES 
        WHERE TABLE_TYPE='BASE TABLE' 
       -- AND TABLE_NAME LIKE 'x%'
"@

$sqlOutputToRun = $nul

invoke-sqlcmd $sql | foreach { 
     $sqlOutputToRun += $_[0] + "`n"
}

$sqlOutputToRun

If you can't live without your cursor why you can't do something like this?

$sql = "
DECLARE @Tables CURSOR;
DECLARE @TableName NVARCHAR(200);
DECLARE @Results TABLE (ResultQuery NVARCHAR(MAX)) 

BEGIN
    SET @Tables = CURSOR FOR
    SELECT TABLE_NAME
    FROM testdb.INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE='BASE TABLE' 
    --AND TABLE_NAME LIKE 'x%'

    OPEN @Tables 
    FETCH NEXT FROM @Tables 
    INTO @TableName
    WHILE @@FETCH_STATUS = 0
    BEGIN
        INSERT INTO @Results (ResultQuery)
        SELECT 'SELECT TOP 1 * FROM test.dbo.' + @TableName

        -- PRINT 'SELECT TOP 1 * FROM test.dbo.' + @TableName
        FETCH NEXT FROM @Tables 
        INTO @TableName 
    END; 

    CLOSE @Tables ;
    DEALLOCATE @Tables;
END;
SELECT * FROM @Results;"
$sqlOutputToRun = Invoke-Sqlcmd -query $sql
$sqlOutputToRun
