Page Comparison

XML files containing one or more data fix sql statements, a sql statement to back up data, and validation statements used to determine whether the data fix should be committed or rolled back.

Object Type Identification

If a file with .xml extension is in datafix folderthe folder specified by the Data Fix Root Source Directory project property, then it is considered a data fix file

...

Name	Code	Description	Default Value
Data Fix Root Source Directory	FDEBS_DATA_FIX_ROOT_SOURCE_DIR	The source directory to recognize files as data fixes	datafix
Data Fix Root Destination Directory	FDEBS_DATA_FIX_DESTINATION_DIR	The destination directory to copy file to. Leave blank to not copy file anywhere

Sample Build Commands

N/A - Build commands not supported for this type.

...

Tag Name	Required	Description
Description	Yes	A description for the data fix being run
FixSQL	Yes	The SQL which implements the data fix. It can be multiple statements delimited by a semicolon or slash
BackupSQL	Yes	SQL to perform necessary backup of data before executing FixSQL	ConnectString	Yes. This must be one valid SQL statement, not followed by a semicolon
ConnectStringProperty	No	The JDBC connection string for the database. Can also use environment instance property	User	YesThe APPS_JDBC_URL environment variable will be used if property is not specified in file
UserProperty	No	User to connect to database with.	Password	YesEnvironment instance property FDEBS_DB_USER will be used if property is not specified in file
PasswordProperty	No	Password for the database user. Must be a FlexDeploy property so it is not in clear text in Environment instance property FDEBS_DB_PASSWORD will be used if property is not specified in file
Validations	Yes	The rule(s) used to validate the data fix before committing changes
Validation	Yes	A single validation rule. See below for more details

A single validation contains the following:

Tag Name	Required	Description
Description	Yes	A description for the validation rule
ValidationSQL	Yes	Select query which is executed before and after the FixSQL is executed, and result is compared with before and after values. This must be one valid SQL statement, not followed by a semicolon
Environment	Yes	The expected results defined by an environment.

See more info below

See below for more details

An environment contains the following:

...

If more than one of these elements are present, all must evaluate to true for the validation to pass.

Data Fix Source Examples

The first example is a simple data fix that updates one row of a table, then verifies only the expected row is updated.
