Why is the federal judiciary of the United States divided into circuits? Both the 4-digit and the 8-digit form can be used to specify UTF-16 surrogate pairs to compose characters with code points larger than U+FFFF, although the availability of the 8-digit form technically makes this unnecessary.

(When continuing an escape string constant across lines, write E only before the first opening quote.) It is your responsibility that the byte sequences you create, especially when using the octal or hexadecimal escapes, compose valid characters in the server character set encoding. The SQL standard will not define a key word that contains digits or starts or ends with an underscore, so identifiers of this form are safe against possible conflict with future extensions of the standard. Also, you will sometimes need to add parentheses when using combinations of binary and unary operators. To ignore or escape the single quote is a common requirement of all. Let's understand through an example by inserting data into an empty table that we created above. 4.1.2.2.

The following example illustrates the correct syntax for the query in Table 1: EXEC SQL select col1 from tab1 where col1 = \; Quotes and double quotes should be escaped using \.

Numeric constants are accepted in these general forms: where digits is one or more decimal digits (0 through 9). With single-quote syntax, each backslash in the above example would have to be written as four backslashes, which would be reduced to two backslashes in parsing the original string constant, and then to one when the inner string constant is re-parsed during function execution.

For example, if you have defined a left unary operator named @, you cannot write X*@Y; you must write X* @Y to ensure that PostgreSQL reads it as two operator names not one. The system uses no more than NAMEDATALEN-1 bytes of an identifier; longer names can be written in commands, but they will be truncated.
