SQL literals can be useful in some cases - as dummy values for select statements where there is exact columns required, unions, expected values for arc.insertFromIterator(src.getStatement(sh)) "insert as select", etc.

The term literal refers to a fixed data value. For example, 123, 'foobar' etc.

Mapping of Qore values to literals:

Qore Type SQL Type Qore Example SQL interpretation
Integer NUMBER as it is 123 123
Float NUMBER as it is 12.3 12.3
Numeric NUMBER as it is 1.2n 1.2
Date String representation of the date using DB native implementation like TO_TIMESTAMP for Oracle. now() to_timestamp('20150421104825000000', 'YYYYMMDDHH24MISSFF6')
Bool Internal representation of the bool value using DB native implementation True 1
String Standard and escaped string literal. No additional literal methods like Oracle's nq{foobar} are supported now "foo bar" 'foo bar'
NULL Direct null literal NULL null
NOTHING Direct null literal NOTHING null
Note
Passing an existing SQL function name as a value to the cop_value() function does not result in function call. The string value is escaped as it is. Example: sysdate becomes 'sysdate'. See example below.

The most useful SqlUtil::cop_value() usage is with cooperation of SqlUtil::cop_as() which allows human readable column name aliases.

Warning
Using SqlUtil::cop_value() without SqlUtil::cop_as() can result in errors depending on the DB backend. For example Oracle's use of cop_value(1), cop_value(True) ends with ORA-00918: column ambiguously defined because both values are interpreted as 1 in the resulting SQL.

)

returns an UpdateOperatorInfo hash for the "substr" operator with the given arguments; returns a substring of a column value

Example:
int rows_updated = t.update(("first_name": uop_substr(1, 1)));
Parameters
startposition where the substring starts
countlength of the substring in characters
nestany nested operation to the operator
Returns
an UpdateOperatorInfo hash corresponding to the arguments for use in update statements

◆ uop_upper()

hash<UpdateOperatorInfo> SqlUtil::uop_upper ( *hash< UpdateOperatorInfo nest)

returns an UpdateOperatorInfo hash for the "upper" operator with the given argument; returns a column value in upper case

Example:
int rows_updated = t.update(("permission_type": uop_upper()));
Parameters
nestany nested operation to the operator
Returns
an UpdateOperatorInfo hash corresponding to the arguments for use in update statements

◆ wop_or()

hash<string, hash<OperatorInfo> > SqlUtil::wop_or ( hash  h1,
hash  h2 
)

returns an OperatorInfo hash with a fake "_OR_" column name; the list of arguments to the function is combined such that each hash in the list generates SQL expressions combined with "and" logic, and each of those clauses is combined with "or" logic; this is for use in where clauses

Example:
*list<auto> rows = table.selectRows(("where": ("name": op_ceq("other_name")) + wop_or(("type": "C", "validation_flag": op_ne(NULL)), ("expiration_date": op_ge(date)))));
Generates:
select * from schema.table where name = other_name and ((type = %v and validation flag is not null) or (expiration_date >= %v))
Parameters
h1the first hash of expressions to combine with "or" logic
h2the second hash of expressions to combine with "or" logic
...remaining expressions to combine with "or" logic
Returns
a hash with an OperatorInfo hash value keyed by a fake column name ("_OR_" with a numeric prefix for uniqueness) for use in a where operation description hash for use in where clauses
Note
a random prefix is used so that multiple uses of the function can be used to generate a single where clause hash
