tMSSqlRow Standard properties
These properties are used to configure tMSSqlRow running in the Standard Job framework.
The Standard tMSSqlRow component belongs to the Databases family.
The component in this framework is available in all Talend products.
Basic settings
Database |
Select the desired database type from the list and click Apply. |
Property type |
Either Built-in or
Repository
.
|
Use an existing connection |
Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined. Information noteNote: When a Job contains the parent Job and the child Job, do the following if you
want to share an existing connection between the parent Job and the child Job (for example,
to share the connection created by the parent Job with the child Job).
For an example about how to share a database connection across Job levels, see Sharing a database connection. |
JDBC Provider |
Select the provider of the JDBC driver to be used, either Microsoft (the default, recommended) or Open source JTDS. When Microsoft is selected, you need to download the Microsoft JDBC Driver for SQL Server on Microsoft Download Center, unpack the downloaded zip file, choose a jar in the unzipped folder based on your JRE version, rename the jar to mssql-jdbc.jar and install it manually. For more information about choosing the jar, see the System Requirements information on Microsoft Download Center. Note that OSGi builds will not include any open source jTDS JDBC driver. If you need to build your Job containing this component as an OSGi bundle, use the official Microsoft JDBC driver; otherwise, this component will work only with Datasource with the jTDS JDBC driver properly installed in Talend Runtime. |
Host | Enter the IP address or the hostname of the database server or the Azure Synapse Analytics to be used. If the SQL Server Browser service is running on the machine where the server resides, you can connect to a named instance through a TCP dynamic port by providing the host name and the instance name in this field in the format of {host_name}\{instance_name}. In this case, you can leave the Port field empty. See SQL Server Browser service for related information. |
Port | Enter the listening port number of the database server or the Azure Synapse Analytics to be used. If the SQL Server Browser service is running on the machine where the server resides, you can connect to a named instance through a TCP dynamic port by providing the host name and the instance name in the Host field and leave this field empty. See SQL Server Browser service for related information. |
Database |
Enter the name of the database |
Schema |
Enter the name of the database schema. |
Username and Password | Enter the authentication data. To enter the password, click the [...] button next to the Password field, enter the password in double quotes in the pop-up dialog box, and then click OK. You can use Type 2 integrated authentication on Windows by adding integratedSecurity=true in the Additional JDBC Parameters field and leave these two fields empty. See section Connecting with integrated authentication On Windows at Building the connection URL for related information. |
Schema and Edit Schema |
A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields. Built-In: You create and store the schema locally for this component only. Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:
|
Table name | Enter the name of the table to be used. |
Turn on identity insert | Select this check box to use your own sequence for the identity value of the inserted records (instead of having the SQL Server pick the next sequential value). |
Query type |
Either Built-in
or Repository
.
|
Guess Query | Click the Guess Query button to generate the query which corresponds to your table schema in the Query field. |
Query | Enter your DB query paying particularly attention to properly sequence the fields in order to match the schema definition. |
Specify a data source alias |
Select this check box and specify the alias of a data source created on the Talend Runtime side to use the shared connection pool defined in the data source configuration. This option works only when you deploy and run your Job in Talend Runtime . This check box is not available when the Use an existing connection check box is selected. |
Data source alias |
Enter the alias of the data source created on the Talend Runtime side. This field is available only when the Specify a data source alias check box is selected. |
Die on error | This check box is selected by default. Clear the check box to skip the row on error and complete the process for error-free rows. If needed, you can retrieve the rows on error via a Row>Rejects link. |
Advanced settings
Additional JDBC parameters |
Specify additional connection properties for the database connection you are creating. The properties are separated by semicolon and each property is a key-value pair. For example, encrypt=true;trustServerCertificate=false; hostNameInCertificate=*.database.windows.net;loginTimeout=30; for Azure SQL database connection. This field is not available if the Use an existing connection check box is selected. |
Authenticate using Azure Active Directory |
Select this option to use Azure Active Directory authentication when establishing the connection. See Azure AD Authentication for related information. This option is only available when Microsoft is selected from the JDBC Provider drop-down list in the Basic settings view. |
Enable always encrypted (Column encryption) | Select this option to use the Microsoft Always encrypted feature to encrypt and protect your
data. To use this option, you need to have previously stored your secrets with
Azure Key Vault:
Some limitations regarding query operations and statements apply to this feature. For the exhaustive list of limitations, see the Microsoft SQL Server documentation. |
Propagate QUERY's recordset | Select this check box to insert the result of the query into a COLUMN of the
current flow. Select this column from the use
column list. Information noteNote: This option allows the component
to have a different schema from that of the preceding component. Moreover, the
column that holds the QUERY's recordset should be set to the type of Object and this component is usually followed by
tParseRecordSet.
|
Set Query Timeout | Select this option to set a timeout period for the query or the batch query.
The Job will be terminated if the query or the batch query is timed out. You can
set the timeout period (in seconds) in the Timeout field. Information noteNote:
|
Use PreparedStatement | Select this check box if you want to query the database using a
PreparedStatement. In the Set PreparedStatement
Parameter table, define the parameters represented by "?" in the
SQL instruction of the Query field in the
Basic Settings tab. Parameter Index: Enter the parameter position in the SQL instruction. Parameter Type: Enter the parameter type. Parameter Value: Enter the parameter value. Information noteNote: This option is very useful if you need to
execute the same query several times. Performance levels are increased
|
Commit every | Number of rows to be completed before committing batches of rows together into the DB. This option ensures transaction quality (but not rollback) and above all better performance on executions. |
tStatCatcher Statistics | Select this check box to collect log data at the component level. |
Global Variables
Global Variables |
NB_LINE: the number of rows processed. This is an After variable and it returns an integer. Note that if the Propagate QUERY's recordset option is selected in the Advanced settings view, this variable returns the number of single ResultSet, which is 1. QUERY: the query statement being processed. This is a Flow variable and it returns a string. ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it. For more information about variables, see Using contexts and variables. |
Usage
Usage rule | This component offers the flexibility of the DB query and covers all possible SQL queries. |
Dynamic settings |
Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio. The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable. For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Dynamic schema and Creating a context group and define context variables in it. |
Limitation |
Due to license incompatibility, one or more JARs required to use this component are not provided. You can install the missing JARs for this particular component by clicking the Install button on the Component tab view. You can also find out and add all missing JARs easily on the Modules tab in the Integration perspective of Talend Studio. For details, see Installing external modules. |
