SQL: Using SQLCMD for Large SQL Scripts

When using SQL Server Management Studio, executing very large queries can bring up a message that the operation cannot be completed, and that there is not enough storage to process the command. An example of a large file would be a sql script that inserts thousands of records into a table.

Rather than using the GUI, we can use Sqlcmd at the command line. Open a CMD Prompt as Administrator. There is no need to change to any specific directory in the CMD prompt. Enter the following, and press Enter:

C:\>sqlcmd -S ServerName -d DataBaseName -i "FolderPath\FileName.sql"

Run a SQL script from the command prompt

-S indicates the name of the SQL Server instance
-d indicates the name of the SQL database
-i indicates the file path to the .sql input file

For more information on available paramteters, enter:

C:\>sqlcmd /?

Enter sqlcmd /? for more information

VBScript: Ensure Backslash Folder Path

Image
To preface what could be regarded as a very small thing, I am reminded of a common turn of phrase concerning the amount of perspiration that should be afforded to the "stuff" belonging to a particular size-category, and pretty sure there was a book written about that topic. Not to come across as disagreeable, but rather to invite a little balance based on my own general observations over time, an increase in cost with things such as time, money, even relationships, can be avoided when the "small stuff" is given the regard that it deserves. One of these tiny details has to do with string variables that reference folder paths within a script. There are times when it is important that a defined directory for a particular folder should and must always end with a backslash. As an example: folderPath = "C:\Example"   Of course, it really is not very difficult to manually enter that backslash into the path. folderPath = "C:\Example\" ...

AutoStore: Workflow Loop Example

Image
Regardless of the programming language, a looping-statement is a common declaration for iterating through collections of things, such as the items of an array, records selected from a database, elements within an XML file, or the files inside a directory. A recent AutoStore challenge was presented where a script was used to fetch data in a process that returned either one or many items. This was the easy part. However, each return record needed to be specific to an individual Route based on one of those items returned. Example Example1@email.com Example1/URL Example2@email.com Example2/URL Example3@email.com Example3/URL Although the captured document being processed would be common for all in the return, the recipient belonging to one of these unique records should not be aware of  nor  receive any of the information that would belong to a different recipient. Because an unknown number of return records would be expected, this presents a challenge due ...

AutoStore: Create a Custom RRT

Image
Have you ever needed to dynamically create a custom RRT for an AutoStore process? In my previous post AutoCapture Default Date , I described my very first AutoStore script where the value of an  Invoice Date  field in an AutoCapture Vendor Invoices  form was assigned a default value of the day prior from the current date. This Invoice Date  needs to be part of the file name, however its format contains slash (/) characters that cannot be part of the file name. So, we'll use the AutoStore VB/JScript process component to create a new RRT that's more friendly. To do so, we'll look at how to do the following: Bring the existing Invoice Date  value into the script Reformat the Invoice Date  to a Windows-friendly file name Output the reformatted Invoice Date to a new custom RRT After adding the VB/JScript process component in between the capture component and the Send to Folder route component of the configuration file, we open the AutoCap...
