TPT Insert

On this Page

Snap type:

Write


Description:

The TPT (Teradata Parallel Transport) Insert Snap allows you to insert the data from input view by executing the script generated using the mapped input field provided by the user. The Snap inserts the data with the values provided in the input view and provides the console output and status code on the output view for any downstream Snap checking for successful execution. 
 
Queries produced by the Snap have the format: 

INSERT INTO "ADW_SNAPL"."employee1" ("empno","empname","sal") VALUES (:"empno",:"empname",:"sal"); 


  • Expected upstream Snaps: Any Snap that provides a document output view, such as Structure or a JSON Generator Snap.
  • Expected downstream Snaps: Any Snap with a document input view
  • Expected input: A stream of documents to be loaded into the table. Each input document contains values for one record in the table.
  • Expected output: A single document containing the console output, return status from tbuild and the script which the Snap submitted to tbuild.


Prerequisites:

TPT Snaps (TPT Insert, TPT Update, TPT Delete, TPT  Upsert and TPT Load) uses the 'tbuild' utility for the respective operations.

In order to use these Snaps in the pipelines, the respective TPT utilities should be installed/available on the Snapplexes. 

All the required TPT utilities must be installed on the node where JCC is running or the Snap simply executes but may not perform the operation. Any utility/library file missing on the node may cause the Snap to perform a failed operation.

Basic steps for installing the TPT utilities:

Procedure to install the Teradata tools and utilities:

  • Download the Teradata Tools and Utilities base such as TTU 16.20.25.00 Linux - Base for Linux environment.
  • If the OS is 64 bit,  install 32 bit support packages on the environment and also any further dependencies
  • Install the Teradata Tools and Utilities (that includes tbuild, fastload, mload etc)
  • The default installation also configures the PATH in the OS

Flow:  If the tbuild or fastload is already available on the OS path then the corresponding TPT Snap can invoke the required utility, however, if these binaries are not available on the OS path, then we need to provide the absolute path of the respective binary in the Snap.


Support and limitations:None.
Account: 

This Snap uses account references created on the Accounts page of  SnapLogic Manager to handle access to this endpoint. See Configuring Teradata Database Accounts for information on setting up this type of account.


Views:
InputThis Snap has at most one Document view.
OutputThis Snap has at most one output view.
Error

This Snap has at most one error view and produces zero or more documents in the view. 
Note: A single document containing the console output and return status from the external TPT application for each input document


Settings

Label


Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.


Schema name



The database schema name. In case it is not defined,  the suggestion for the table name will retrieve all the table names of all the schemas. The property is suggestible and will retrieve available database schemas during suggest values.

The values can be passed using the pipeline parameters but not the upstream parameter.

Example: SYS

Default value: [None] 

Table name

Required. Name of the table to insert records into.

The values can be passed using the pipeline parameters but not the upstream parameter.

Example: people

Default value: [None] 

Create table if not present
 

Whether the table should be automatically created if not already present.

Default value: [None] 

TBUILD location
 

Location of the tbuild application. 

The location will be on the Snapplex.

Example: /usr/bin/tbuild

Default value: [None] 

Fetch metadata delay (seconds)
 

The wait time in seconds to be used before fetching metadata to avoid conflicts while performing Teradata parallel executions in a pipeline.

Default value: 0 

Snap execution

Select one of the three modes in which the Snap executes. Available options are:

  • Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.
  • Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Example


 In this pipeline, the TPT Insert Snap inserts the records on the TPT table via the upstream JSON Generator Snap.

The JSON Generator Snap passes the values to updated in the records of the TPT Table.  


 


The TPT Insert Snap inserts the records into the table Insert Sample3 under the schema, ADW SNAPL.


The successful execution of the pipeline displays the below output preview:

4.24 Patch

424patches8799 Latest
  • Enhanced the Teradata Execute Snap by adding a new field, Advanced options, which extends support with microsecond precision for TIMESTAMP data type.
  • Fixed an issue in the TPT Load Snap where the Snap failed to load data into the table while creating an output.
  • Fixed an issue with the TPT Load Snap wherein now a null value is loaded as null and empty string is loaded as empty string.

    • This fix may cause existing pipelines to fail if empty string values are expected to be loaded as null.

    • Following are the new configurations:

      • VARCHAR QuotedData= Optional

      • VARCHAR OpenQuoteMark= \”

      • VARCHAR NullColumns= Yes

4.24main8556

Enhanced the Teradata Select Snap to return only the selected output fields or columns in the output schema (second output view) using the Fetch Output Fields In Schema check box. If the Output Fields field is empty all the columns are visible.

4.23main7430
 
Stable

Fixes the multi-line value issue and issue in the TPT Load Snap where the Snap writes null for both an empty string and null values in the input data. The fix for this issue was to add the following three lines in the script and wrap all the values in double quotes unless they are null while writing the input data into a temp CSV file. 
VARCHAR QuotedData = 'Optional',
VARCHAR OpenQuoteMark = '\"'
VARCHAR NullColumns = 'Yes'

This fix may cause existing pipelines to fail if empty string values are expected to be loaded as null.
