AppendQueryInteger(const TUint32 &, TDes &, TBool &, const TUint32 &, const TUint32 &, const TDesC &)

void	AppendQueryInteger	(	const TUint32 &	aValue,
			TDes &	aSql,
			TBool &	aMultiple,
			const TUint32 &	aFlag,
			const TUint32 &	aSetCol,
			const TDesC &	aColName
		)	[private]

Appends an integer-based query key field to an SQL query string.

Parameters

const TUint32 & aValue	The integer value which will be added to the query.
TDes & aSql	The SQL query string.
TBool & aMultiple	EFalse, if there is only one query key in the query string. Otherwise, ETrue.
const TUint32 & aFlag	The flag value corresponding to the query key.
const TUint32 & aSetCol	A constant value indicating whether or not a specific column is set.
const TDesC & aColName	The column name of the query key.

AppendQueryStringL(const TDesC &, TDes &, TBool &, const TUint32 &, const TUint32 &, const TDesC &)

void	AppendQueryStringL	(	const TDesC &	aValue,
			TDes &	aSql,
			TBool &	aMultiple,
			const TUint32 &	aFlag,
			const TUint32 &	aSetCol,
			const TDesC &	aColName
		)	[private]

Appends an string query key to an SQL query string.

Parameters

const TDesC & aValue	The string value which will be added to the query.
TDes & aSql	The SQL query string.
TBool & aMultiple	EFalse, if there is only one query key in the query string. Otherwise, ETrue.
const TUint32 & aFlag	The flag value corresponding to the query key.
const TUint32 & aSetCol	A constant value indicating whether or not a specific column is set.
const TDesC & aColName	The column name of the query key.

CreateSqlStatementLC(CDecisionFilter &, RBuf &)

void	CreateSqlStatementLC	(	CDecisionFilter &	aFilter,
			RBuf &	aSql
		)	[protected]

Creates an sql statement from a given filter.

Parameters

CDecisionFilter & aFilter	A filter object used to create the SQL statement.
RBuf & aSql	The newly created SQL statement.

CreateViewL(CDecisionFilter &)

IMPORT_C CDecisionView *

CreateViewL

(

CDecisionFilter &

aFilter

)

Generates an SQL view rowset to the decision table by using a filter. The view rowset contains a set of rows which depend on the filter.

Parameters

CDecisionFilter & aFilter

A filter object to query the decision database

DoubleSingleQuotesL(const TDesC &, RBuf &)

void	DoubleSingleQuotesL	(	const TDesC &	aSource,
			RBuf &	aDestination
		)	[protected]

Copies a source descriptor into a destination descriptor. If a single quote character is found an extra single quote is copied to the destination. Because, it is not possible to search for a string in SQL with single quote (').

Parameters

const TDesC & aSource	A source descriptor.
RBuf & aDestination	A destination descriptor.

GetComparisonOperator(const TUint32 &)

const TDesC *

GetComparisonOperator

(

const TUint32 &

aFlag

)

const [private]

Finds and returns the correspondent comparision operator string.

Parameters

const TUint32 & aFlag
