This ftl library contains utility macros to generate SQL snippets.


generateWhereClause (MACRO)

Generates WHERE clause from given WHERE clause conditions

Parameters:

  • conditions REQUIRED - list of conditions

  • indentation OPTIONAL - the wanted indentation level (defaults to zero)

Returns:

if conditions is empty, returns nothing
otherwise prints:
WHERE with initial indentation and each entry of conditions list with
initial indentation + 1 on separate line and
from second item onwards will begin with AND


generateJoinClause (MACRO)

Generates JOIN clause from given JOIN clause conditions

Parameters:

  • conditions REQUIRED - list of conditions

  • indentation OPTIONAL - the wanted indentation level (defaults to zero)

Returns:

if conditions is empty, returns nothing
otherwise prints:
each entry of conditions list with initial indentation on separate line and
from second item onwards will begin with AND


generateOrderByClause (MACRO)

Generates ORDER BY clause from given ORDER BY clause conditions

Parameters:

  • conditions REQUIRED - list of conditions

  • indentation OPTIONAL - the wanted indentation level (defaults to zero)

Returns:

if conditions is empty, returns nothing
otherwise prints:
ORDER BY with initial indentation and each entry of conditions list with
initial indentation + 1 on separate line and
from second item onwards will begin with ,


generateEntityAttributeList (MACRO)

Generates list of attribute names

Parameters:

  • attributes REQUIRED - the attributes involved

  • attributeType OPTIONAL - attribute type only to be printed (defaults to "")

  • showDeletedStatusList OPTIONAL - whether to show the deleted or non-deleted attributes

  • prefix OPTIONAL - prefix to be used infront of the attribute name (defaults to "")

  • encapsulate OPTIONAL - whether the attributes are to be encapsulated or not (defaults to false)

  • indentation OPTIONAL - amount of indentation used (defaults to 1)

Returns:

lists all the attributenames, separated with comma


generateTargetAttributeSetByNameList (MACRO)

Generates list of attribute names in set attribute format

Parameters:

  • attributes REQUIRED - the target attributes

  • trgPrefix OPTIONAL - the target prefix (defaults to "")

  • srcPrefix OPTIONAL - the source prefix (defaults to "src")

  • encapsulate OPTIONAL - whether the attributes are to be encapsulated or not (defaults to false)

  • indentation OPTIONAL - amount of indentation used (defaults to 0)

Returns:

lists all the attribute names in set attribute format, eg trg_prefix.attribute = src_prefix.attribute


generateTargetAttributesTransformList (MACRO)

This macro is to collect the transformations for wanted attributes

Parameters:

  • attributes REQUIRED - the target entity attributes involved

  • prefix OPTIONAL - prefix to be used with source attributes (defaults to "")

  • overridePrefixTransformationMap OPTIONAL - overriding transformation type for attributes with specific prefix (defaults to {})

  • overrideAttributeTypeTransformationMap OPTIONAL - overriding transformation type for attributes with specific attribute type (defaults to {})

  • showTargetName OPTIONAL - whether target attribute name should be shown after the the transformation formula (defaults to true)

  • indentation OPTIONAL - the amount of indentation to be used (defaults to 0)

Returns:

comma separated list of target attribute specific transformations


generateSetTargetAttributeByTargetTransformationList (MACRO)

This macro is to collect the set list of target attribute and its transformation

Parameters:

  • attributes REQUIRED - the target entity attributes involved

  • prefix OPTIONAL - prefix to be used with source attributes (defaults to "")

  • overridePrefixTransformationMap OPTIONAL - overriding transformation type for attributes with specific prefix (defaults to {})

  • overrideAttributeTypeTransformationMap OPTIONAL - overriding transformation type for attributes with specific attribute type (defaults to {})

  • encapsulate OPTIONAL - whether target attribute should be encapsulated (default to false)

  • indentation OPTIONAL - the amount of indentation to be used (defaults to 0)

Returns:

comma separated list of target attribute specific transformations in format <field> = <formula>,<field> = <formula>
