The
ODBC Data Object
Odbc (open database connectivity) uses any compliant ODBC database driver. Most major database vendors offer ODBC drivers with their system. Although ODBC is typically slower than the newer methods of interfacing to databases, it is usually very easy to find an ODBC driver for your database given its wide, standards-based acceptance. Odbc provides a common interface for accessing SQL based database systems.
Properties
Action |
Describes the action to take for output streams. Ignored for input streams. Valid options are:
| ||||||||||||||
AppendSQLWith |
This property will only be used when employing SQL Batching - when the RowsPerTransaction property is greater than 1. This is the character that will be appended to the end of each SQL statement in the batch. Default = ; | ||||||||||||||
Catalog |
Database catalog name. For instance: Northwind. Some databases do not use the concept of catalogs in which this property should be left blank. | ||||||||||||||
ColumnLayout |
The column layout (or file structure) of the table. Click on the Ellipse (...) button to fill in the column layout, or select an existing column layout from the repository. See also (Column level Write Flags) | ||||||||||||||
CommandTimeout |
Specify the maximum number of seconds to wait for any command that is sent to the database. Once this time is exceeded you will receive a timeout error. | ||||||||||||||
ConnectString |
(read only) This property displays the ConnectString that will be used to connect to the data source. It is built automatically by deriving the information from the other properties. | ||||||||||||||
ConnectStringOtherParams |
Any custom parameters to be included in the ConnectString. (example: see OleDb) | ||||||||||||||
CreateTable |
The create table property allows you to create your output table in the database during the job execution. You can also choose to DROP the table prior to creating it. The create table wizard will also generate your create table statement for you based on the pre-defined ColumnLayout. | ||||||||||||||
DataSourceName |
The ODBC Data Source Name to use for this object. ODBC Data Sources are setup in the ODBC Data Source Administrator typically located in the Windows Control Panel / Administrative Tools. Click the ellipse button (...) on the the property to get a list of ODBC Data Sources on your system. | ||||||||||||||
DateTimeFormat |
DateTime format mask to use when loading the data. This is a useful way to format all columns defined as DateTime to standard format. It saves you time from having to format each column individually in the Join object. If the column is left blank the date will be read as it is received from the database. Click on the ellipse to use the mask builder tool. | ||||||||||||||
RowsPerTransaction |
This data object supports batch SQL transactions which can greatly enhance the loading speed of a BlueSky Integration Studio job. Simply enter the number of SQL statements to place in the internal queue before submitting them to the database. For instance; by entering 1000 in this property, BlueSky Integration Studio will not attempt to send the sql commands until 1000 records have been read from the input source, or until the last record is read (i.e. if there are only 300 input records, of course it will then write them to the database). The database can process 1000 sql statements at once, much faster than 1000 individually sent sql statements. (see also: What is SQL Batching?) | ||||||||||||||
Signon |
The user name and password to use to connect to the database. The password is hidden in this property. Click the Ellipse (...) button on the property where you can enter both the user name and hidden password. | ||||||||||||||
Tablename |
Database table name | ||||||||||||||
TextEncoding |
| ||||||||||||||
Comments |
Comment area to give descriptive text about the data object and its purpose. | ||||||||||||||
Alias |
Alias identifier. Aliases are used on all design objects to simplify coding and to ensure each object has a unique identifier. | ||||||||||||||
Name |
Descriptive name for this object. You can enter any text to describe the object | ||||||||||||||
GenerateSql |
Yes / No. By default, the data object will automatically generate the SQL Select statement for you deriving the information from other properties such as the Tablename and ColumnLayout properties. By changing this property to No you can hand-code the SQL statement in the SQLSelect property window. This gives you complete flexibility to enter SQL statements that join multiple tables together and/or use database optimizer hints. | ||||||||||||||
OnPostDMLFailure |
ContinueOn / AbortJob : When DML (data manipulation language) statements are entered into the PostDML property, you can control whether your job continues executing if the DML statement fails for some reason. DML statements include any valid UPDATE, INSERT or DELETE type of SQL statements. (see Pre / Post DML example) | ||||||||||||||
OnPreDMLFailure |
ContinueOn / AbortJob : When DML (data manipulation language) statements are entered into the PreDML property, you can control whether your job continues executing if the DML statement fails for some reason. DML statements include any valid UPDATE, INSERT or DELETE type of SQL statements. (see Pre / Post DML example) | ||||||||||||||
PostDML |
DML (data manipulation language) statement to execute after the job or Join object completes. Any valid INSERT, UPDATE or DELETE type of SQL Statement. (see Pre / Post DML example) | ||||||||||||||
PreDML |
DML (data manipulation language) statement to execute before the job or Join object starts. Any valid INSERT, UPDATE or DELETE type of SQL Statement. (see Pre / Post DML example) | ||||||||||||||
PreTransactionSQL |
Some databases, like Oracle, require that multiple batched SQL statements are wrapped in a SQL code block. For instance; when using SQL Batching in Oracle, you must set this property to BEGIN (see How to use SQL Batching in Oracle) so that the SQL Statements are within a PL/SQL code block. This property will only be used when RowsPerTransaction is greater than 1. | ||||||||||||||
PostTransactionSQL |
Some databases, like Oracle, require that multiple batched SQL statements are wrapped in a SQL code block. For instance; when using SQL Batching in Oracle, you must set this property to END; (see How to use SQL Batching in Oracle) so that the SQL Statements are within a PL/SQL code block. This property will only be used when RowsPerTransaction is greater than 1. | ||||||||||||||
SQLOutputFile |
(output only). This SQLOutputFile is the path and filename to a file where you want the actual SQL statements being generated to be logged. This can come in handy when you are trying to debug a job, or some problematic data. In production it is best to leave this property empty. For instance: c:\jobsql.log | ||||||||||||||
SQLSelect |
The SQL Select statement that will be used for data objects used in input streams. The SQL statement is built automatically by deriving information from other properties such as the Tablename and ColumnLayout properties. You can override this SQL Statement by setting the GenerateSQL property to No. |
