SQL Emojis - 📊 Understanding Array Fields and SQL Functions

 📊 Understanding Array Fields and SQL Functions

Array fields are dynamic data containers often presented in grids on property sheets, representing various details like CCTV survey specifics, manhole survey inlets, and outlets within InfoAsset Manager. Each row in these arrays corresponds to a specific data point within these surveys or objects, akin to the way objects themselves have named fields.

📍 Flag Arrays: Flags associated with an object can also be treated as arrays. They contain two essential fields - "value" and "name" (where "name" is read-only).

SQL provides several ways to access and work with the fields within these arrays.

🔍 1. Detecting Data in the Array: To check if the array contains any data, you can use the function ANY with the array's name followed by '.'. For example, ANY(details.) will return true if there are any records in the array, otherwise, it returns false.

📏 2. Counting Rows in the Array: Counting the number of rows in the array is done using the COUNT function with the array's name followed by '.'. For instance, COUNT(details.) calculates the number of rows in the "details" array.

📊 3. Aggregate Functions: SQL offers various aggregate functions that evaluate an expression for each row in the array and then perform a collective action with all the results. These functions can be applied to numeric, date, and string fields. Some key aggregate functions include:

• ANY: Returns true if the expression is true for any row.
• ALL: Returns true if the expression is true for all rows.
• COUNT: Returns the count of records that satisfy the expression.
• MAX: Retrieves the maximum value from the array.
• MIN: Retrieves the minimum value from the array.
• AVG: Computes the average of non-NULL values.
• FIRST and LAST: Capture values from the first and last records in the array.

📦 Using 'Bare' Array Field Values: You can also use values from array fields outside of aggregate functions in expressions. The expression is evaluated for each record within the array. Keep in mind that when using expressions, it's crucial to precisely define your query, especially when dealing with tests other than equality.

📝 Setting Values in Array Fields: You can set values in array fields by including them in an assignment clause. This allows you to modify data in multiple records at once. The SET clause can be used with or without a WHERE clause, and you can use array fields to specify the conditions under which the SET clause is applied.

🔁 Interaction Between 'Bare' Array Fields and Aggregate Functions: When using array field values in both the WHERE and SET clauses, the aggregate functions in the SET clause are only evaluated for records that meet the conditions specified in the WHERE clause.

For example, if you use the query SET user_number_1 = COUNT(details.*) WHERE details.code = 'DES', it will set user_number_1 to the number of "details" records with the code "DES." The same effect can be achieved with SET user_number_1 = COUNT(details.code='DES').

An alternate way to calculate this without using a 'bare' array field would be SET user_number_1 = SUM(IIF(details.code='DE', details.service_score, 0)).

However, if an aggregate function is used in the WHERE clause, it will be applied to all records within the array field.

🔗 In Summary: SQL's array handling capabilities provide a powerful means to manipulate and analyze complex data structures efficiently. Using aggregate functions and 'bare' array field values wisely can help you unlock the full potential of your data.

🎯 Improving Pump Simulation in SWMM 5

 🎯 Improving Pump Simulation in SWMM 5

• Goal: Enhance the simulation of variable speed pumps in SWMM 5 for better accuracy.
• Current Setup: 🔄 Users currently adjust three pumps (Pump1, Pump2, and Pump3) based on the depth in the Wet Well. This method relies on three distinct pump curves.
• Proposed Solution: 🧠 Use SWMM 5's Real-Time Control (RTC) feature to simulate pump settings with a single control curve, streamlining the process.
• How it Works:
  • 📊 The pump flow is determined using the Pump Curve (refer to Figure 2).
  • 🛠️ This flow is then fine-tuned according to the Pump Setting (detailed in Figure 3).
  • 💡 Each pump operates with its unique control curve. These curves dictate when the pump activates or deactivates based on the Wet Well's depth (Check Figures 4, 5, and 6 for the respective pumps).
• Benefits: 🌊 This method ensures a more consistent flow (visualized in Figures 7 and 8). Moreover, it offers flexibility to simulate varying pump speeds using a singular pump curve, depending on the active pump.

Conclusion: 🚀 Utilizing the RTC feature in SWMM 5 paves the way for a more precise and streamlined simulation of variable speed pumps with just one foundational pump curve.

🌐 Introduction to InfoSurge 🌐 - Emoji Version

 🌐 Introduction to InfoSurge 🌐

 

Welcome to the realm of InfoSurge, a beacon of light in the turbulent waters of water distribution systems! 🌊 When pressure surges aka waterhammer knock at the doors, the tranquility of the system trembles. These uninvited guests bring along a troupe of troubles - failing pumps, pipe ruptures, and the notorious backflow of dirty water (pathogen intrusion) into the kingdom of clean water! 🚿 Pump startups and shutdowns are like transient storms, leaving trails of increased leakage and a dent in the reliability of our water guardians. 🌪️

A dreaded scenario - uncontrolled pump shutdown (downsurge) may summon the dreaded water-column separation, a precursor to catastrophic pipeline failures due to the ensuing severe pressure rises following the collapse of the vapor cavity. 💥

 

🚀 Rise of InfoSurge 🚀

 

Fear not, for the InfoSurge is here, a result of meticulous efforts to craft a comprehensive modeling application. It stands as a vigilant knight, ready to be wielded by engineers and scientists to combat the transient operation demons haunting the pipe systems. 🛡️ Vapor cavitation and liquid column separation, the dark forces, are explicitly modeled, thus letting the pressure surges due to vapor cavity collapse be evaluated rightfully. 💫 This mighty program is designed to quickly and accurately compute pressures and flows throughout the piping kingdom during transient operations, and evaluate alternate operational scenarios and surge protection schemes like a wise sage. 🧙

 

💫 Journey into the Abyss of Hydraulic Transients 💫

 

Hydraulic transients are akin to disturbances in the peaceful fluid realm, caused during the transition from one steady-state to another. 🔄 The principal components of these disturbances are pressure changes triggered by the propagation of pressure waves throughout the distribution system. 🌊 These pressure waves, akin to messages from the deep, continue to travel with the velocity of sound until they are dissipated down to the level of the new steady-state by the action of damping or friction forces. 🎶 Only if the flow is regulated with a gentle touch, it's possible to transition smoothly from one steady-state to another without inviting the wrath of large fluctuations in pressure head or pipe velocity. 🔄

 

🌪️ The Five Horsemen of Disturbances 🌪️

 

Disturbances in the water realm can be stirred by:

1. Pump startup or shutdown: The awakening or the slumber of the pump giants! 🎛️
2. Valve opening or closing (variation in flow area): The gatekeepers’ dance! 🕺
3. Changes in boundary pressures (reservoir level, pressure tank, etc.): The shifting sands of pressure landscapes! 🏜️
4. Rapid changes in demand conditions (e.g., hydrant flushing): The thirst of the land! 🚰
5. Changes in transmission conditions (e.g., pipe break): The breaking point! 💔

These disturbances can morph into serious tsunamis for water utilities if not recognized and addressed with proper analysis and design considerations. 🌊 Our hydraulic systems must be fortified castles, designed to endure both normal and abnormal operations, and shielded to withstand adversities like power failure, pipeline fracture, and more. 🏰

 

🛡️ The Arsenal of Transient Mitigation 🛡️

 

Here are the three sacred design considerations to ward off transient conditions:

1. Alteration of pipeline characteristics (e.g., pipe diameter): Shaping the veins of our water body! 🔄
2. Improvement in valve and pump control procedures: Mastering the rhythm of flow! 🎶
3. Design and installation of surge protection devices: Crafting the shields against surges! 🛡️

InfoSurge unveils a treasure chest of devices to control pressure and flow transients, including but not limited to open surge tanks, closed surge vessels, bladder tanks, hybrid tanks, bypass lines, check valves, feed tanks, air release/vacuum valves, pressure relief valves, and surge anticipation valves. 🗝️
