SELECT * FROM patient_data WHERE lower(full_name) LIKE '%ducker_' Is the last letter an "s" or a "z"? Let's use a wildcard in a query to solve this issue: Say you want to obtain every record for a patient with the last name of "Duckerz" but you don't remember exactly how the name spelled. Let's see another example of the LIKE operator at work. It doesn't matter what (or how many) characters come before "smith". Can also be used anywhere in a string.īasically, we used the % wildcard to tell SQL to find any " full_name" record that has "smith" at the end of it. Can be used at the beginning, middle, or end of a string. If you're not familiar with SQL wildcards, have a look at the following table before we proceed: Wildcard SELECT * FROM patient_data WHERE lower(full_name) LIKE '%smith' The idea is to obtain all records with a full_name ending in 'smith' (remember to use the lower function here). To solve this problem, we'll use the LIKE operator and a wildcard character (%). SELECT * FROM patient_data WHERE lower(full_name) = 'john smith' That's because "John Smith" has a different name in another record: "Johnny Smith". The previous approach worked for Agnes' records, but it won't work for John Smith. SELECT * FROM patient_data WHERE lower(full_name) = 'agnes jason' By adding the LOWER function, which essentially converts a string to all-lowercase letters, we can eliminate the good doctor's inconsistent capitalization.
Since we want both records, we must change the query. However, if we look at the table, we can see there is another record for an "AGNES Jason". This gives us one result for "Agnes Jason". SELECT * FROM patient_data WHERE full_name = 'Agnes Jason' Let's try the following query to analyze what's happening: This is a serious problem, but we can fix it with SQL string functions. When the doctor needs all the records related to one patient, he may retrieve the wrong ones. He's particularly weak with remembering names, so the same patient could have more than one name in his database.
He misspells words, uses uppercase letters randomly, and makes a few typos. As a consequence, the data quality suffers.
He manually types his notes into the database instead of automating it.

The table contains the patient's full name, the date of the visit, the doctor's diagnosis, the suggested treatment, and any prescribed drugs.Įvery time a patient goes to his office, the doctor creates a new record. Even better, you can swipe left on any contact in the list to remove the birthdate information if you don’t know the person well enough to care.Let me paint you a picture of a doctor who stores all his patient data in a single table. It lists everyone whose contact card contains a birthdate, in chronological order.

Whereas Cardhop on the Mac is a menu bar app that focuses on favorite and recently used contacts, Cardhop for iOS provides four different contact views and a Settings screen, accessed by tapping toolbar icons at the bottom of its main list on the iPhone or the bottom of the left-hand sidebar on the iPad.
