Sql-server – How to insert ‘&’ symbol in data

For something like this the optimal solution of course is to control your input. That said, the reality is you have to parse the supplied input.

For something as complex as your parsing, I'd skip the Derived Column transformation and go straight for a Script transformation. I select my source column, Input and create three output columns: number, trash and Interval. number and Interval will hold the parsed values while trash will only be populated when the script can't make heads or tails from the input.

I use two member variables, numbersRegex and periodDomain. periodDomain is just a list with the acceptable values. For string comparisons, I force everything to lowercase and hope for English. numbersRegex is a regular expression that is used to identify digits in a string.

For every row that comes in, the script will split the Input value based on whitespace. For each of those tokens, I test whether the token has a digit in it. If it does, we'll call the GetBiggestNumber method. Otherwise, we'll call the ValidatePeriodDomain Once all the tokens have been processed, then it's important to make certain both values have been set.

GetBiggestNumber attempts to look at all the groupings of number and find the largest set.

ValidatePeriodDomain attempts to compare the current value to a known list of acceptable values.

        int? foo = null;

        foreach (string token in parts)
        {
            // try to do something with it
            // If the token has a digit in it, then we'll extract the largest value
            // if no digits, then the first token matching our domain is preserved
            if (this.numbersRegex.IsMatch(token))
            {
                foo = GetBiggestNumber(token);

    {
        return (this.periodDomain.Contains(token.ToLower()));
    }

    private int? GetBiggestNumber(string token)
    {
        int? bigOne = null;
        int? current = null;
        // Get all the groups of numbers and compare them
        foreach (Match item in this.numbersRegex.Matches(token))
        {
            current = int.Parse(item.Value);
            if (!bigOne.HasValue)
            {
                bigOne = current;

            if (current.Value > bigOne.Value)

Using the above script, you can see how it slices and dices the Input data. I made a minor change between the code that generated the below screenshot and what's posted. I observed that the input value 9000 was assigned to Row.number but as that Row never had an Interval assigned, I deferred the actual Row population to the end of the script (it was in the

You have to use convert DT_WSTR to DT_DBTIMESTAMP. You can find BOL reference here.

for e.g.instead of "Getdate()" use your Date_Column

(DB_TIMESTAMP)((DT_WSTR,4)YEAR(GETDATE()) + RIGHT("0" + (DT_WSTR,2)MONTH(GETDATE()),2) + RIGHT("0" + (DT_WSTR,2)DAY(GETDATE()),2) + (DT_WSTR,10) Time_Column)

Also, you can use the Data Conversion transformation, which is probably easier if you are only changing the data type.

EDIT: You can also look for an option of SSIS GoogleAnalyticsSource from codeplex.
