Import CSV Files into SQL Server using SSMS (SQL Server Management Studio)

 SSMS tool is used for writing queries. Apart from this, it is very helpful tool to import the CSV data into SQL Server.

Suppose we have a CSV file like this which is having double quotes and comma separated and it has headers also.

To Load this file into SQL Server, We can import using the below.

Database --> Tasks --> Import Data

It opensup the wizard.

Click next. Select Flat File as Data Source and select the file path,

Format :  Delimited. In the above CSV the delimiter is comma. 

Header Row Delimeter :  It is comma

Header rows to skip :  We have headers in the csv file so it should be zero

Select check box column names in the first row data

Click on columns to preview

If you want to change anything, use the advanced tab 

To preview rows clik on preview. 

Click next and select SQL native client and SQL server instance name. We windows or SQL based on the usage. Select database. 

Click next and sleect target name. We can rename the table also if it new table. Since this table not exist in db ,SQL will create automatically.

If we want to change anything in destination mapping we can use edit mapping. If we are sure it is not exist we can use create destination table or use other options based on usage.

Run immediately to run the package.

Click Finish to start the package.

The package run completed successfully.

We can see verify the table data by running the select in the target database.

Java Program to Connect SQL Server

 First time I tried to connect SQL Server using Java

'

Faced below issue while trying to connect

This driver is not configured for integrated authentication. We need to download the jdbc libraries and place in this path.

Dowloaded file

Place file in jre path

"connection refused: getsockopt. verify the connection properties. make sure that an instance of sql server is running on the host and accepting tcp/ip connections at the port. make sure that tcp connections to the port are not blocked by a firewall.".

This is due to TCP/IP Disabled. Enabled TCP/IP and restarted services.

Add jdbc drivers to connect SQL server. Download latest libraries from SQL server

PowerShell SQLInvoke-Sqlcmd Scripts

1) PowerShell Command to display date by Connecting SQL Server 

Invoke-Sqlcmd -Query "SELECT GETDATE() AS TimeOfQuery" -ServerInstance "DESKTOP-H8VE8AJ"

2) PowerShell Command to execute SQL Satement and save output to a file

Invoke-Sqlcmd -InputFile "C:\Users\OneDrive\Resumes\SQL Server Management Studio\Profit.sql" | Out-File -FilePath "C:\Users\OneDrive\Resumes\SQL Server Management Studio\Profit.rpt"

3) PowerShell command to pass the vairables

$StringArray = "MYVAR1='Machinename'", "MYVAR2='InstanceName'","MYVAR3='ServerName'

Invoke-Sqlcmd -Query "SELECT SERVERPROPERTY(`$(MYVAR1)) AS ComputerName,

SERVERPROPERTY(`$(MYVAR2)) AS InstanceName,

SERVERPROPERTY(`$(MYVAR3)) AS ServerName;" -Variable $StringArray -ServerInstance "DESKTOP-H8VE8AJ"

4) 

Openssl command for certficates and key generation

 1) To connect secure port using SSL we can use the below command

openssl s_client -connect hostname/localhostip:portnumber

ex :  openssl s_client -connect 127.0.0.1:443

2) To show the certificate from website we can use the below command

openssl s_client -showcerts -connect 127.0.0.1:443

3) To Print Certificate we can use OpenSSL

echo | openssl s_client www.google.con -connectwww.google.con:443 2>dev/null | openssl x509 text

4) To covert pkcs12 to pem format we can use OpenSSL

openssl pkcs12 -in "certificate in pkcs12 format" -nodes -out "new_cert.pem"

5) to convert the certificate from crt to pem format

openssl x509 -in "cert.crt" -out "cert.pem"

6) to convert the certificate from cer to pem format

openssl x509 -in "cert.cer" -out "cert.pem"

7) to convert the certificate from pem to der format

openssl x509 -outform der -in "cert.pem" -out "cert.der"

8)  Openssl can used to generate public private key pair. Below uses pkcs8 format

openssl genrsa 4096 | openssl pkcs8 -topk8 -inform PEM -out rsa_key_4096.p8 -nocrypt

openssl rsa -in rsa_key_4096.p8 -pubout rsa_key_4096.pub

9)  Openssl can used to generate public private key pair. Below uses pkcs8 format

DB2 Commands

 1) db2level

This will show the DB2 product version.

2) db2 list node directory

This will show nodeDirectory list that contains hostname, service name, protocol, node name

3) db2 list database directory

This will show database name , database version, authetication type etc details

4)  db2 connect to "databasename" user "üsername" using "Password"

This will connect to database

Curl Commands

 1) Curl Command to download the data from a internet site.

curl  -O https://testserver.com.au/file.zip 

sometimes if secure option is enabled it will not allow to download the file. We may get error

curl failed the legitimacy of the server and therefore could not establish a secure connection to it.  so to fix this we use -k option.

curl  -k -O https://testserver.com.au/file.zip
