Class SqlFunctions

java.lang.Object

org.apache.calcite.runtime.SqlFunctions

public class SqlFunctions
extends Object

Helper methods to implement SQL functions in generated code.

Not present: and, or, not (builtin operators are better, because they use lazy evaluation. Implementations do not check for null values; the calling code must do that.

Many of the functions do not check for null values. This is intentional. If null arguments are possible, the code-generation framework checks for nulls before calling the functions.

toInt

public static int toInt(Date v)

Converts a SQL DATE value from the Java type (Date) to the internal representation type (number of days since January 1st, 1970 as int) in the local time zone.

See Also:

• toInt(java.sql.Date, TimeZone)
• converse method

toInt

public static int toInt(Date v,
 TimeZone timeZone)

Converts a SQL DATE value from the Java type (Date) to the internal representation type (number of days since January 1st, 1970 as int).

The Date class uses the standard Gregorian calendar which switches from the Julian calendar to the Gregorian calendar in October 1582. For compatibility with ISO-8601, the internal representation is converted to use the proleptic Gregorian calendar.

If the date contains a partial day, it will be rounded to a full day depending on the milliseconds value. If the milliseconds value is positive, it will be rounded down to the closest full day. If the milliseconds value is negative, it will be rounded up to the closest full day.

Since a time zone is not available, converts the timestamp to represent the same date and time as a Unix timestamp in UTC as the Date value in the local time zone.

The Date class uses the standard Gregorian calendar which switches from the Julian calendar to the Gregorian calendar in October 1582. For compatibility with ISO-8601, converts the internal representation to use the proleptic Gregorian calendar.

toLong

public static long toLong(Timestamp v)

Converts a SQL TIMESTAMP value from the Java type (Timestamp) to the internal representation type (number of milliseconds since January 1st, 1970 as long).

• converse method

toLong

public static long toLong(Timestamp v,
 TimeZone timeZone)

Converts a SQL TIMESTAMP value from the Java type (Timestamp) to the internal representation type (number of milliseconds since January 1st, 1970 as long).

For backwards compatibility, time zone offsets are calculated in relation to the local time zone instead of UTC. Providing the default time zone or null will return the timestamp unmodified.

The Timestamp class uses the standard Gregorian calendar which switches from the Julian calendar to the Gregorian calendar in October 1582. For compatibility with ISO-8601, the internal representation is converted to use the proleptic Gregorian calendar.

toLongOptional

public static @PolyNull Long toLongOptional(@PolyNull Timestamp v)

The Unix date should be the number of days since January 1st, 1970 using the proleptic Gregorian calendar as defined by ISO-8601. The returned Date object will use the standard Gregorian calendar which switches from the Julian calendar to the Gregorian calendar in October 1582.
