Is there any function to compare two strings

Re: About Strings

Former Member — Thu, 08 Mar 2007 04:47:38 GMT

Yes we have

CO, CP , NA , EQ, CS

all these can be used for individual character comparison and for string comparison also..

for more information check this link...

Hi Ravikanth.....

Strings can also be compared with Relational operators like <, > <= >= ........

Just try it once......

Hi,

Try using the FM SOTR_STRING_PARSER_COMPARE.

1. CO (Contains Only):

c1 contains only characters in the string c2.

The comparison takes into account the full length of c1,

including blanks at the end.

If the result of the comparison is negative, the system

field SY-FDPOS contains the offset of the first character in

c1 which is not also in c2.

If the result of the comparison is positive, the system

field SY-FDPOS contains the length of c1.

The comparison is case-sensitive.

Examples:

'ABCDE' CO 'XYZ' is false; SY-FDPOS = 0.

'ABCDE' CO 'AB' is false; SY-FDPOS = 2.

'ABCDE' CO 'ABCDE' is true; SY-FDPOS = 5.

CN (Contains Not only):

"c1 CN c2" is equivalent to "NOT ( c1 CO c2 )".

c1 contains not only characters from c2.

If the result of the comparison is positive, the system

field SY-FDPOS contains the offset of the first character in

c1 which is not also in c2.

If the result of the comparison is negative, the system

field SY-FDPOS contains the length of c1.

CA (Contains Any):

c1 contains at least one character from the string c2.

The comparison takes into account the full length of c1,

including blanks at the end.

If the result of the comparison is positive, the system

field SY-FDPOS contains the offset of the first character in

c1 which is also in c2.

If the result of the comparison is negative, the system

field SY-FDPOS contains the length of c1.

The comparison is case-sensitive.

Examples:

'ABCDE' CA 'CY' is true; SY-FDPOS = 2.

'ABCDE' CA 'XY' is false; SY-FDPOS = 5.

NA (contains Not Any):

"c1 NA c2" is equivalent to "NOT ( c1 CA c2 )".

c1 contains no characters from c2.

SY-FDPOS is set accordingly.

CS (Contains String):

c1 contains the character string c2.

Trailing blanks in c1 and c2 are ignored.

If the result of the comparison is positive, the system

field SY-FDPOS contains the offset of the first character of

c2 in c1.

If the result of the comparison is negative, the system

field SY-FDPOS contains the length of c1.

The comparison is not case-sensitive.

Examples:

'ABCDE' CS 'CD' is true; SY-FDPOS = 2.

'ABCDE' CS 'XY' is false; SY-FDPOS = 5.

'ABAAA' CS 'AB ' is true; SY-FDPOS = 0.

' ABC' CS ' AB' is true; SY-FDPOS = 1.

'ABC DEF' CS ' ' is true; but: SY-FDPOS = 0,

since ' ' is interpreted as a trailing blank and is thus

ignored.

NS (contains No String):

"c1 NS c2" is equivalent to "NOT ( c1 CS c2 )".

c1 does not contain c2.

SY-FDPOS is set accordingly.

CP (Contains Pattern):

c1 matches c2.

The pattern c2 can contain ordinary characters and

wildcards.

'*' stands for any character string and '+' denotes any

character.

If the result of the comparison is positive, the system

field SY-FDPOS contains the offset of the first character of

c2 in c1. The wildcard character '*' at the beginning of the

pattern c2 is ignored when determining the value of

SY-FDPOS.

If the result of the comparison is negative, the system

field SY-FDPOS contains the length of c1.

Examples:

'ABCDE' CP 'CD' is true; SY-FDPOS = 2.

'ABCDE' CP '*CD' is false; SY-FDPOS = 5.

'ABCDE' CP '+CD' is true; SY-FDPOS = 0.

'ABCDE' CP '+CD*' is false; SY-FDPOS = 5.

'ABCDE' CP 'BD*' is true; SY-FDPOS = 1.

The character '#' has a special meaning. It serves as an

escape symbol and indicates that the very next character

should be compared "exactly".

Hi,

You can use = operator to compare strings..

Example

DATA: V_STRING1 TYPE STRING.

DATA: V_STRING2 TYPE STRING.

V_STRING1 = 'ABC'.

V_STRING2 = 'ABC'.

IF V_STRING1 = V_STRING2.

WRITE: / 'TRUE'.

ELSE.

WRITE: / 'FALSE'.

ENDIF.

Hi Ravi,

Yes there are few FM's to compare strings but it depends what is your requirement.

Check

DX_MAP_COMP_STRINGS

/SAPDMC/LSMW_COMP_STRINGS

But better to the string comparison operators as mentioned in the above reply.

Cheers
