Methods of Data Pull from Excel to Database Tables

Methods of Data Pull from Excel to Database Tables:
There are several methods that can be used to pull the data from an excel sheet into a database table.
  1. Using SQL Server's Import and Export wizard that lets us choose the excel file from which the data to be pulled. Each sheet of the excel file can be distinguished from the sheet name during the mapping step in the wizard. A sheet, for example sheet 1 is referred as Sheet1$ and so is Sheet2$ and so on.
  2. Creating an SSIS package, that lets us choose the data source to be an excel file and the data destination that would be a database table through a OLE DB Connection properly set up.
  3. Another way would be using a linked server. Here, select the OLE DB provider to be Microsoft Jet 4.0 OLE DB Provider. Select the Product Name as Excel, Data source is the full path of the Excel file and the provider string is Excel 8.0. This configuration is as mentioned in the below picture.


 And later, click OK, which will complete the configuration of the Linked Server for the Excel file. To import the data to a table we can use a select into query as

SELECT * INTO data_frm_excel FROM EXCELLINK...Sheet1$

This select statement selects the data from the linked excel file from sheet 1. EXCELLINK is the linked server name we have chosen here which could be given as ever required on their own choice.

And there are other methods that can be used to load the data to tables in the same way using Programming concepts which aren't explained here. For further reference, go to the following link.

Deferred prepare could not be completed

This is usually an error that is encountered while querying a remote database on a different server instance which says OLEDB provider "SQLNCLI" for linked server "ABCD" returned message "Deffered prepare could not be completed" Msg 8180, Level 16, State 1, Line 1 Statement(s) could not be prepared. This is the way I could rectify, though this is not the lone mistake that gives this error every time. Just set the default to the database that is being querying to the user through which the Linked server is connecting to the database.

Script level upgrade for database 'master' failed because upgrade step 'sqlagent100_msdb_upgrade.sql'

As huge a database grows, that tedious are regular DBA activities become. Besides, a warehouse database, can grow with no bounds to challenge.  There was a patching on one of our databases, SP3 for SQL Server 2008 R2, which was failing due to the error below. As the error says, MASTER the heart of SQL Server  “Script level upgrade for database 'master' failed because upgrade step 'sqlagent100_msdb_upgrade.sql' encountered error 2627, state 1, severity 14. This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the 'master' database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion. Cannot recover the master database. SQL Server is unable to run. Restore master from a full
