The exponent has and optional leading minus sign. The mantissa has an optional leading minus sign followed by one digit to the left of the decimal point, and the minimal number of digits greater than zero to the right. Otherwise Databricks SQL uses a mantissa followed by E and an exponent. If the absolute number is less that 10,000,000 and greater or equal than 0.001, the result is expressed without scientific notation with at least one digit on either side of the decimal point. If the targetType is DECIMAL(p, s) with s greater 0, a decimal point is added and trailing zeros are added up to scale. The result is the literal number with an optional minus-sign and no leading zeros except for the single digit to the left of the decimal point. If the targetType is a STRING type (Databricks SQL) and sourceExpr is of type: > SELECT cast(INTERVAL '1:30.5' MINUTE TO SECOND AS DECIMAL(5, 2)) > SELECT cast(INTERVAL '1-2' YEAR TO MONTH AS INTEGER) > SELECT cast(TIMESTAMP' 00:00:00' AS SMALLINT) > SELECT cast(TIMESTAMP' 00:00:01' AS LONG) If the lower_unit is SECOND, fractional seconds are stored to the right of the decimal point.įor all other intervals the result is always an integral number. Given an INTERVAL upper_unit TO lower_unit the result is measured in total number of lower_unit. This version is available in the Preview channel. Requires: SQL warehouse version 2022.35 or higher. If the result is outside the range of targetType, an overflow error is raised. Otherwise, the result is rounded to a fit the available scale of targetType. If targetType is an integral numeric, the result is truncated to a whole number. The result is the number of seconds elapsed between 00:00:00 UTC and sourceExpr. Use try_cast to turn overflow and invalid format errors into NULL. If the value is outside the range of the targetType, an overflow error is raised. If sourceExpr doesn’t comply with the format for literal values, an error is raised. SourceExpr is read as a literal value of the targetType. Use try_cast to turn overflow errors into NULL. If the value is outside the range of targetType, an overflow error is raised. Otherwise, the result is sourceExpr rounded to a fit the available scale of targetType. If targetType is an integral numeric, the result is sourceExpr truncated to a whole number. The result is a NULL of the specified numeric type. If the targetType is a numeric and sourceExpr is of type: Rules and limitations based on targetType numeric The following combinations of data type casting are valid: Source (row) Target(column) targetType: The data type of the result.Casts the value expr to the target data type type.
