                         boolean ignoreTimezone,
                         SnowflakeDateTimeFormat.ParserGSInteractions gsInteractions)

Parses a string into an SFTimestamp.

Parameters:

stringToParse - String to parse.

timeZone - Timezone to use if it's not found in the string. If null, GMT is used by default.

centuryBoundary - If > 0, defines the century boundary.

formatType - Type(s) of the format(s) desired for auto parsing.

ignoreTimezone - If the string contains a timezone, ignore it.

gsInteractions - Object containing configuration and usage tracking for GS, or null if no special handling is needed.

Returns:

Parsed SFTimestamp. Can be null if nothing parsed. If the string had a timezone which is not ignored, it will be set.

parse

public SFTimestamp parse(String stringToParse,
                         TimeZone timeZone,

effectiveSpecializedTimestampFormat

public static String effectiveSpecializedTimestampFormat(String specialized,
                                                         String generic)

Returns effective String format for TIMESTAMP_*_OUTPUT_FORMAT, assuming that if the specialized format is empty, the generic format should be used.

Parameters:

specialized - Specialized format, e.g. TIMESTAMP_NTZ_OUTPUT_FORMAT

generic - Generic format, usually TIMESTAMP_OUTPUT_FORMAT

Returns:

Effective format
