Method Summary

Modifier and Type	Method and Description
static java.lang.Integer	getExpressionDataType(java.lang.String expression, java.lang.String objectName) Validates the passed expression by executing a JDBC query against the passed object, Returns the resulting data type obtained from the ResultSetMetaData.
static boolean	isCompatibleDataType(java.lang.String mxDataType, int jdbcDataType) Evaluates whether the specified Maximo data type is compatible with the specified type provided by the JDBC driver.
static boolean	isCompatiblePrecision(java.lang.String mxDataType, int jdbcDataType) Determines if the mxDataType that is selected is less precise than the JDBC type.
static boolean	isJDBCDate(int type) Determines whether the passed SQL data type from ResultSetMetaData is a date type.
static boolean	isJDBCNumeric(int type) Determines whether the passed SQL data type from ResultSetMetaData is numeric.
static boolean	isJDBCPrecise(int type) Determines whether the JDBC type is a type with a large precision.
static boolean	isMxDate(java.lang.String type) Determines whether the passed Maximo data type is a date type.

Method Detail

isCompatibleDataType

public static boolean isCompatibleDataType(java.lang.String mxDataType,
                                           int jdbcDataType)

Evaluates whether the specified Maximo data type is compatible with the specified type provided by the JDBC driver.

Parameters:

String - mxDataType the Maximo data type selected for the expression

int - jdbcDataType the data type returned by the JDBC ResultSetMetaData for the calculated column

Returns:

true if the data types are compatible, false if not.

isCompatiblePrecision

public static boolean isCompatiblePrecision(java.lang.String mxDataType,
                                            int jdbcDataType)

Determines if the mxDataType that is selected is less precise than the JDBC type.

Parameters:

mxDataType -

jdbcDataType -

Returns:

getExpressionDataType
