public class SQLQuery
extends StyleElement

An sql:query element in the stylesheet. For example:

   <sql:query column="{$column}" table="{$table}" where="{$where}"
                 xsl:extension-element-prefixes="sql"/ >

 
(result with HTML-table-output)
   <sql:query column="{$column}" table="{$table}" where="{$where}"
                 row-tag="TR" column-tag="TD"
                 separatorType="tag"
                 xsl:extension-element-prefixes="sql"/ >

Field Detail

connection

Expression connection

column

Expression column
selected column(s) to query


table

Expression table
the table(s) to query in


where

Expression where
conditions of query (can be omitted)


rowTag

String rowTag

colTag

String colTag
name of element to hold the rows


disable

boolean disable
name of element to hold the columns

Constructor Detail

SQLQuery

public SQLQuery()
Method Detail

isInstruction

public boolean isInstruction()
Determine whether this node is an instruction.

Overrides:
isInstruction in class StyleElement
Returns:
true - it is an instruction

mayContainTemplateBody

public boolean mayContainTemplateBody()
Determine whether this type of element is allowed to contain a template-body

Overrides:
mayContainTemplateBody in class StyleElement
Returns:
true: yes, it may contain a template-body (this is done only so that it can contain xsl:fallback)

prepareAttributes

public void prepareAttributes()
                       throws TransformerConfigurationException
Description copied from class: StyleElement
Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Specified by:
prepareAttributes in class StyleElement
Throws:
TransformerConfigurationException

validate

public void validate()
              throws TransformerConfigurationException
Description copied from class: StyleElement
Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:
validate in class StyleElement
Throws:
TransformerConfigurationException

compile

public Instruction compile()
                    throws TransformerConfigurationException
Description copied from class: StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.

Specified by:
compile in class StyleElement
Returns:
either an Instruction, or null (indicating a no-op).
Throws:
TransformerConfigurationException
