When converting from datetime or smalldatetime values, use an appropriate char or varchar data type length to truncate unwanted date parts. When converting smalldatetime to character data, the styles that include seconds or milliseconds show zeros in these positions. The HH:MM offset, in the + or - direction, indicates other time zones. ĩ Use the optional time zone indicator Z to make it easier to map XML datetime values that have time zone information to SQL Server datetime values that have no time zone. When casting character data representing only date or only time components to the datetime or smalldatetime data types, the unspecified time component is set to 00:00:00.000, and the unspecified date component is set to. This value doesn't render correctly on a default US installation of SSMS.Ĩ Only supported when casting from character data to datetime or smalldatetime.

For example, the value T18:26:20.000 displays as T18:26:20.ħ In this style, mon represents a multi-token Hijri unicode representation of the full month name. SQL Server uses the Kuwaiti algorithm.Ħ For a milliseconds ( mmm) value of 0, the millisecond decimal fraction value won't display. For conversion from datetime or smalldatetime to character data, see the previous table for the output format.ĥ Hijri is a calendar system with several variations. We recommend specifying four-digit years.ģ Input when you convert to datetime output when you convert to character data.Ĥ Designed for XML use. This allows for the consistent treatment of dates.

SQL Server provides the two digit year cutoff configuration option to change the cutoff year used by SQL Server. Many client applications, including those based on Automation objects, use a cutoff year of 2030. That means that SQL Server interprets the two-digit year 49 as 2049 and the two-digit year 50 as 1950. Includes all ( yy) (without century) styles and a subset of ( yyyy) (with century) styles.Ģ The default values ( 0 or 100, 9 or 109, 13 or 113, 20 or 120, 23, and 21 or 25 or 121) always return the century ( yyyy).īy default, SQL Server interprets two-digit years based on a cutoff year of 2049. ODBC canonical (with milliseconds) default for time, date, datetime2, and datetimeoffsetġ These style values return nondeterministic results. Since the second record in this table isn't a case insensitive variation of true and false, an error is returned for this record.Ĭonverts the single column table of numbers to a single column table of boolean value.SQL Server supports the date format, in Arabic style, with the Kuwaiti algorithm. Single column tables aren't supported with untyped values, and instead the formula ForAll( Table(ParseJSON( "" )), Boolean( ThisRecord.Value ) ) or ForAll( ParseJSON( "" ), Boolean( ThisRecord ) ) should be used.Ĭonverts the single column table of text strings to a single column table of boolean values.Ĭonverts the single column table of text strings to a single column table of boolean values. String or number values are accepted as outlined for the String and Number overloads described earlier.Ĭonverts the text string "true" to a boolean value.Ĭonverts the text string "false" to a boolean value.Ĭonverts the text string "TRUE" to a boolean value.Ĭonverts the text string "TrUe" to a boolean value.Īttempts to convert the text string "Truthful" to a boolean value, but since it isn't a case insensitive variation of true and false, an error is returned.Ĭonvert the blank value to a boolean value.Ĭonvert the number -1234 to a boolean value.īoolean( ParseJSON( "" ).bool )Īttempts to convert the untyped value "true" (a JSON string) to a boolean value, but since it isn't a valid boolean value in JSON, an error is returned.Īttempts to convert an array of boolean values to a single column table. For JSON, JSON boolean values true, false, and null are accepted, corresponding to true, false, and blank values in Power Fx. Acceptable values are dependent on the untyped provider. blank values are accepted and converted to a blank. 0 is converted to false and all other numbers are converted to true. blank and empty string is also accepted and converted to a blank.

Must be a case insensitive version of "true" or "false". The Boolean function is useful when an explicit conversion is desired or when using an untyped value. For example, If( "true", 1, 0 ) will return 1 as the text string "true" is automatically converted to a Boolean. In most cases, type coercion happens automatically and the Boolean function need not be used explicitly. A Boolean value is true, false, or blank. Use the Boolean function to convert other types to a Boolean value. Converts a text string, number, or untyped value to a Boolean value.
