Sets the default value if a reply is not given. See the Oracle Database Administrator's Guide and the Oracle Database SQL Language Reference for information on Oracle Database date formats. DATE without a specified format defaults to the NLS_DATE_FORMAT of the current session. Oracle Database date formats such as "dd/mm/yy" are valid when the datatype is DATE. See COLUMN FORMAT for a complete list of format elements. The format element must be a text constant such as A10 or 9.999. If an attempt is made to enter a greater number precision than is specified by the number format, an error message is given and the value must be reentered. ![]() If an attempt is made to enter more characters than are specified by the char format, an error message is given and the value must be reentered. If the reply does not match the specified format, ACCEPT gives an error message and prompts again. Specifies the input format for the reply. BINARY_DOUBLE is a floating-point number that conforms substantially with the Institute for Electrical and Electronics Engineers (IEEE) Standard for Binary Floating-Point Arithmetic, IEEE Standard 754-1985. Makes the variable a BINARY_DOUBLE datatype. BINARY_FLOAT is a floating-point number that conforms substantially with the Institute for Electrical and Electronics Engineers (IEEE) Standard for Binary Floating-Point Arithmetic, IEEE Standard 754-1985. Makes the variable a BINARY_FLOAT datatype. If the reply is not a valid DATE format, ACCEPT gives an error message and prompts again. If a multi-byte character set is used, one CHAR may be more than one byte in size. If the reply does not match the datatype, ACCEPT gives an error message and prompts again. If variable does not exist, SQL*Plus creates it. Represents the name of the variable in which you wish to store a value. Reads a line of input and stores it in a given substitution variable. We're not taking comments currently, so please try again later if you want to add a comment.ACC variable | CHAR | DATE | BINARY_FLOAT | BINARY_DOUBLE] format] default] ] PS - your LiveSQL link appears to be invalid. ![]() If you want to know more about these, the following articles give a good comparison: These are critical for security and performance. So the user input never becomes part of the executed statement. ![]() In these applications, you can't use substitution variables. The vast majority of the time it's called via an application written in some other language (C, Java. Substitution variables are handy for command line scripts where you want users to supply some of their own values.Ä«ut it's rare for people to call PL/SQL from the command line. LiveSQL has no back-and-forth to do this. They're called substitution variables because the client replaces the &variable with the value you pass. To use these you need to use an interactive environment link SQLcl, SQL*Plus or SQL Developer.įor example, when I run it in SQLcl I get:Ä¥ dbms_output.put_line('Your age is:' || age) The ampersand indicates a substitution variable. ORA-06550: line 4, column 9: PLS-00103: Encountered the symbol "&" when expecting one of the following: ( - + case mod new not null continue avg count current exists max min prior sql stddev sum variance execute forall merge time timestamp interval date pipe ![]() My code is given in bold and the error displayed is shown in italics:Äbms_output.put_line('Your age is:' || age) I have modified the code accordingly yet the error doesn't get resolved. I found a similar question on this portal 'Dynamic variable initialization', it said. However, I always encountered the error which fails to recognize the '&' symbol and suggests me various other symbols that should be used instead. I tried my best to use the given format (link of the Oracle Live session has been provided with my query). I was watching YouTube tutorials on Oracle PL/SQL and I came across this feature that uses the placeholder to assign a value to a variable by reading it from the user at the run time.
