Specified by:

createPatternMatchQuery in interface QueryBuilder

Parameters:

pValueString - the string which is searched for the substring. This must have been created with createPropertyQueryExpression() or createConstantQueryExpression

pPatternString - the pattern to search for. This must have been created with createConstantQueryExpression or createParameterQueryExpression

pMatchingOperation - the type of match to search for

pIgnoreCase - if false match is case-sensitive, if true match is case-insensitive

createDirectSqlQuery

public Query createDirectSqlQuery(java.lang.String pQuery,

                           throws RepositoryException

This is a variation of the SqlPassThroughQuery that can call stored procedures as well as execute straight sql. Unlike the SqlPassThroughQuery, this query can preload property information if more than just the id property is selected. This is indicated by the pReturnedProps property. Also, these Queries can be cached and can have property dependencies like other queries

Parameters:

pQuery - the SQL string to execute

pReturnedProps - an array of property descriptors that are expected to be returned from the query when the SQL is executed. Note that this may or may not include an id property if one is defined for the view this Builder pertains to. Also note that the order that the properties appear in this array is the order that the associated columns for the properties must be returned. These properties must fit the following rules: 1) Must not be transient 2) Must not be multi-valued 3) Must be readable

pDependentProps - an array of property descriptors that this query will depend upon for caching. So if any of these properties change for a given item that is returned from this query, it will be removed from the query cache

pInputParameterClasses - an array of Classes that correspond to the types of the input parameters in this query, if any. The first element in the array maps to the first input parameter in the query, and so on

Returns:

a query that executes straight sql

Throws:

a - RepositoryException if the arguments are incorrect

RepositoryException

createDirectSqlQuery

public Query createDirectSqlQuery(java.lang.String pQuery,
                                  RepositoryPropertyDescriptor[] pReturnedProps,
                                  RepositoryPropertyDescriptor[] pDependentProps,
                                  java.lang.Class[] pInputParameterClasses,
                                  boolean pIsStoredProcedure)
                           throws RepositoryException

This is a variation of the SqlPassThroughQuery that can call stored procedures as well as execute straight sql. Unlike the SqlPassThroughQuery, this query can preload property information if more than just the id property is selected. This is indicated by the pReturnedProps property. Also, these Queries can be cached and can have property dependencies like other queries

Parameters:

pQuery - the SQL string to execute

pReturnedProps - an array of property descriptors that are expected to be returned from the query when the SQL is executed. Note that this may or may not include an id property if one is defined for the view this Builder pertains to. Also note that the order that the properties appear in this array is the order that the associated columns for the properties must be returned, if pStrictOrdering is true. These properties must fit the following rules: 1) Must not be transient 2) Must not be multi-valued 3) Must be readable

pDependentProps - an array of property descriptors that this query will depend upon for caching. So if any of these properties change for a given item that is returned from this query, it will be removed from the query cache

pInputParameterClasses - an array of Classes that correspond to the types of the input parameters in this query, if any. The first element in the array maps to the first input parameter in the query, and so on

pIsStoredProcedure - if this is true, then the pQuery string is assumed to be a call to a stored procedure. A JDBC CallableStatement will be used to issue this SQL, so users must make sure that these calls are escaped properly. Usually this means that calls must be enclosed by curly braces '{}' e.g. {call myprocedure}. If this is false, then it's assumed that a regular sql statement is being passed in. NOTE: When using a stored procedure, the expected return value is a valid single ResultSet

Returns:

a query that executes straight sql

Throws:

a - RepositoryException if the arguments are incorrect

RepositoryException
