The ToDate operator converts the value of its argument to a Date value. For String values, The operator expects the string to be formatted using the ISO-8601 date representation: YYYY-MM-DD See the Formatting Strings topic in the CQL Reference (Appendix B) of the CQL Specification for a description of formatting strings. In addition, the string must be interpretable as a valid date value. Note that the operator can take datetime formatted strings and will ignore the time portions. If the input string is not formatted correctly, or does not represent a valid date value, the result is null. As with date literals, date values may be specified to any precision. For DateTime values, the result is equivalent to extracting the Date component of the DateTime value. If the argument is null, the result is null.
