This interface allows tag handlers implementing it to receive values for parameter markers ("?") in their SQL statements.
This interface is implemented by both <sql:query> and
<sql:update>. Its addSQLParameter()
method
is called by nested parameter actions (such as <sql:param>)
to substitue PreparedStatement
parameter values for
"?" parameter markers in the SQL statement of the enclosing
SQLExecutionTag
action.
The given parameter values are converted to their corresponding SQL type (following the rules in the JDBC specification) before they are sent to the database.
Keeing track of the index of the parameter values being added is the responsibility of the tag handler implementing this interface
The SQLExcecutionTag
interface is exposed in order
to support custom parameter actions which may retrieve their
parameters from any source and process them before substituting
them for a parameter marker in the sQL statement of the
enclosing SQLExecutionTag
action
