QuotedStr

function QuotedStr(const S: string): string;

It encloses a string in single quotes (') and escapes any existing single quotes within the string by doubling them. This is particularly useful when a string is to be used as a constant in an SQL query or another language, ensuring that the string is safely quoted.

Usage:

• QuotedStr takes a string and surrounds it with single quotes.
• If the string already contains single quotes, they are doubled, making it a valid constant in languages like SQL.

Example
TRObject Syntax

var
  originalStr, quotedStr: string;
{
  originalStr = 'O''Reilly';  // O'Reilly is a common example with an apostrophe
  quotedStr = QuotedStr(originalStr);
  ShowMessage(quotedStr); // Output: 'O''Reilly'
}

Base Syntax

var
  originalStr, quotedStr: string;
begin
  originalStr := 'O''Reilly';  // O'Reilly is a common example with an apostrophe
  quotedStr := QuotedStr(originalStr);
  ShowMessage(quotedStr); // Output: 'O''Reilly'
end;
