access string functions
In order to split the data in a field, you will need to use a combination of the following Access functions: 1  Left. Syntax: Left (string, length) Returns a specified number of characters from the left side of a string. 2  InStr. Syntax: InStr([start, ]string1, string2[, compare]) If N_or_S is a number, returns a string representation of the hexadecimal value of N, where N is a longlong (BIGINT) number. This is equivalent to CONV(N,10,16). If N_or_S is a string, returns a hexadecimal string representation of N_or_S where each character in N_or_S is converted to two hexadecimal digits. Returns a set value (a string containing substrings separated by .,. characters) consisting of the strings that have the corresponding bit in bits set. str1 corresponds to bit 0, str2 to bit 1, and so on. NULL values in str1, str2, ... are not appended to the result. Allows you to search for a character or string within a string, and returns a number telling you the first occurence of one string within another. Right Syntax: Right (string, length) Returns a specified number of characters from the right side of a string. Len Syntax: Len(string) Returns a length of a string. In our sample table, we have a field that shows the names of employees. Extract the First Name (Access Query Tip) In your query, create a field and use a combination of the Left and InStr functions to extract the First name. Left([strName],InStr([strName],” “)-1) Here’s a screen shot of the function in the Query Design Grid. Here’s a screen shot of the result. In order to split the data in a field, you will need to use a combination of the following Access functions: 1  Left. Syntax: Left (string, length) 2  InStr. Syntax: InStr([start, ]string1, string2[, compare]) 3  Right. Syntax: Right (string, length) 4  Len. Syntax: Len(string) CHAR_LENGTH(str) Returns the length of the string str measured in characters. A multi-byte character counts as a single character. This means that for a string containing five two-byte characters, LENGTH() returns 10, whereas CHAR_LENGTH() returns 5. Unlike Excel, Access doesn’t have a simple way to do this. In order to split the data in a field, you will need to use a combination of the following Access functions: Left Syntax: Left (string, length) Returns a specified number of characters from the left side of a string. InStr Syntax: InStr([start, ]string1, string2[, compare]) Access String Functions.
